I started training with Dennis in mid-December, first with a 3-session intro pack before investing in the 24-session package.  I'm probably 2/3rds my way through that training package now and I have to say that I've been really happy with my progress.  My goal is weight loss and muscle building.  I didn't see much weight loss the first six weeks or so mainly because we were adjusting my macros and nutrition to see what body needed, but my fitness level and strength have definitely improved a ton.  Now that we've dialed in my macros we're starting to see the pounds come off.

I've worked out with a variety of trainers over the past 10+ years, some were from a company gym, 24 Hour Fitness, Fitness SF and a DIAKADI private trainer. Dennis is definitely one of the better trainers I've had.  He's a professional trainer vs. a part-timer like you generally find at a chain gym and that means he's really focused on you hitting your goals.  I can check in with him anytime with questions, which is great.  He's actually the first of all my trainers who's suggested tracking macros and paying close attention to my nutrition.  

I'm really happy with our progress to date and will definitely give another update in a couple months.  If you're shopping for a trainer I suggest you give Dennis a call.

Backstory: A friend of mine got into a weight loss/exercise journey and looked so great that I wanted to get back on the fitness train. It has been around ten years since I last truly worked out with weights. I messaged Dennis requesting a consultation, but he informed me he was completely booked at the time, but I would be placed on a wait list if I gave my availability. Dejected, I didn't feel like looking again for another trainer (after reading all his perfect reviews, how could I go through all that trouble to look for another one?). After a couple of weeks, I decided to put on my big girl pants and would do a search later on in the day. It must have been my lucky day because later on that day (before my an extended search), he texted me with some availabilities.

I hopped on the dates he provided and bought a full package. I have just completed the full package and purchased another one - and will probably be a very long term client. Why, you ask?

Okay yes, I will admit that counting calories and macros was very much not my style, but holy bananas - I did not even realize how many calories I consumed on the regular. In the less than 2 months, I have dropped over 5lbs, gained a bunch of strength, and feel like Dennis is such an amazing, supportive person to have as a personal trainer. I went from not being able to do a single sit-up to being able to do 4 sets of 20 on my own. (I laugh-cry about it now.)

Service: Dennis will gently guide you throughout your journey. He knows what you can handle and what you can't. He'll push you, but in a very encouraging, affirmative way. He recommended some exercise equipment for me to use on the days I'm not working with him. I went from just walking around 5 mi./day to adding 4 weight days and 2 cardio(ish) days (sorry Dennis, I tried so hard but I really hate cardio) and following really closely to the nutritional plan and I've seen a huge improvement on my body - some of my clothes don't even fit in the same way anymore. AND! He also explains what he's doing, what muscles are targeted, and he adjusts weights more or less, depending on how well you're doing. He also keeps detailed notes on what was done.

Gym: It's a fully loaded gym with weights, machines, and treadmills. He sprays and wipes down the mats before each usage. While masking is optional at this point, he respectfully keeps his on for the time being.

Honestly, if you can get a spot with him, pull the trigger. It's worth every dollar as long as you can be truthful to yourself on what you're able to do, stick to the plan, and use all the tips he has. You will get to your journey with him, I am certain of it. I am recommending him to everyone!

I came across Dennis' personal training services on Yelp and I am very happy with all the sessions I've had the past few weeks. I was relatively active doing spinning, bootcamp and OrangeTheory classes for years. However, things changed when the pandemic hit and I resorted to a more sedentary lifestyle with the switch from 100% working from home. I needed to get back into a structured routine to shed some weight I gained from the past year and a half.

Dennis is very pleasant and he gives very insightful advice on nutrition, muscle building, proper form, and these workouts are quite challenging. He cares about making sure every minute of your workout is maximized. I'm excited to continue working out with him to achieve some short term and long term goals.

I have been training with Dennis for half a year and it has been such a great experience! He makes working out interesting and fun. He motivates me and is always encouraging. I am a mom of two toddlers, and getting back in shape has been a big challenge. I am so happy that I can finally getting back to my old dresses. The result gives me more motivation for back at the exercise. He really pays attention to your body, provides good feedback on form to make sure I do everything to get the max results and not hurting myself.

Five stars doesn't do Dennis justice. I came to Dennis because I needed a structured program with my workouts including my nutrition. After talking with Dennis during the consultation, I decided to sign up for his online coaching program for 8 weeks. Dennis set me up with a workout routine including my nutrition based on the info I provided him: physique pictures, weight, height, age, work schedule, and gym equipments that I have at home. Till this day, Dennis has always kept me on my feet and always checked up on me. It feels awesome to have Dennis as my coach. He's been nothing but helpful, responsive, and always answering my questions when I needed help with my nutrition and workouts. I highly recommend Dennis if you're looking for a trainer!

Dennis has been training me for about 8 months and I am more than happy with my experience. Since I've started with him, I have noticed a significant difference. I have been losing a good amount of weight while, at the same time, feeling myself growing stronger. He keeps me accountable with living a healthier lifestyle while still being understanding of when I don't keep up with things in my day to day life. I normally hate working out and I'm still very surprised that I don't dread coming to the sessions at all. The training sessions are tailored to your abilities and I'm always very impressed with the way Dennis is able to push me just the right amount. If you're hesitant about personal training, I highly recommend you take the plunge with Dennis.

Started training with Dennis a few weeks ago! Really enjoying my experience!
Dennis approach goes beyond his hour with you, he also incorporate nutrition and tracking macros and cardio on your own time. I feel confident that I will reach my fitness goals with Dennis!

I started training with Dennis just after recovering from a full body injury and had lost a lot of muscle, and wanted to mindfully get back into working out. Dennis made sure to craft a plan for me that took into account my injuries, and I was still able to make a lot of progress despite that. I'm now fully recovered and continuing to see and feel new muscle definition on a regular basis. Dennis truly cares about his clients' progress, and is very in tune with how you're feeling or your energy for the day. He is a great listener and always respectful, and provides encouragement in a way that makes you forget you're working so hard. He makes you feel confident about training and would never push you to the point of injury. He has also done a great job making training work even in the midst of Covid. I look forward to every session, even knowing I'll be sore the next day!

During my first session with Dennis we had a discussion of my goals. What did I want to achieve through a training program? I had 3 goals: 1) to build upper body strength 2) to gain weight and 3) to become more conscious about eating healthy. I was impressed by Dennis' directness and honesty. He said it would take time but it was important to track my macros and not  to overdo my daily activity level because I am very thin and older. (I'm 60 years old!) After a year and a half, we've seen improvement. I can see and feel the changes in my body. I've got more definition in my skinny arms and have gained weight (not reached our goal yet, though). More importantly, I feel good after each session! Although I complain at times during the training (I hate 'curls'!), Dennis challenges me. He pushes me a little bit more but never more than I can handle. I've come a long way and it's due to the hard work with Dennis as my trainer.

I just finished my introductory package with Dennis and I am so excited to purchase my next round of sessions!

I have always been yo-yo dieting and recently had a weight plateau that I couldn't shake. I'd run miles and still didn't feel like there was any difference to my body. I've always been intimidated by weight training, and I just assumed I'd never be able to get into it because I wasn't strong enough and just not in shape.

Dennis has been able to help me weight train and opened my eyes to a whole new workout routine. I can now feel more confident when I walk into a weight room and no longer feel embarrassed that I don't know what I'm doing or hurting myself in the process.

I lost 4 lbs in just two weeks with the help of his training and guidance :) and I didn't even exercise outside of our PT sessions. I am excited to continue training with weights as it feels so rewarding to strengthen your body and be able to see such rapid changes!

I highly-recommend Dennis if you're trying to lose weight or just want to learn more about weightlifting techniques that you can add to your workout.

Thanks so much for everything, Dennis!

After losing quite a bit of weight and getting borderline underweight, I went to see Dennis to get out of my skinny-fat funk and start shaping my body. Working with him has really changed my approach to fitness. He's setup a workout plan for me, taking into account my body type and my mentality towards working out. It's been really successful so far. Seeing him every week keeps me motivated to not only push myself in our sessions but to also follow his regimen while I'm in the gym on my own. I love being able to track my progress as I feel greater endurance and am able to lift heavier weights week after week.

Dennis is very passionate about his job and loves to see progress in his clients. If you're in the gym week after week not really sure why you're going through the motions, go talk to Dennis - Going to the gym will no longer be a chore but a hobby!

I have trained with Dennis a couple of times and I am happy with my experience. Dennis is very respectful of people's lifestyles and will adjust training and recommendation based on that. He is also a really nice person and considerate (he remembered my dog :crying:) Anyway i highly recommend Dennis!

I met Dennis a few months ago as I was looking for a personal trainer to reach my goals.  He came highly recommend and I decided to give him a try.  Personally I could not be more happier with the way things went.  His all about accountability and making sure you say on track.  Dennis also caters workouts to your needs and pushes you when necessary.  

His macro program also helped me learn how to eat healthier and I haven't felt this good years.  His also very accessible when it comes to communication. Thanks Dennis!

Dennis has been great at helping me achieving my goals to not feel so lost in a gym about what to do, and having a regular workout routine.  I had done private training before working with Dennis but the workouts never stuck and I always felt like I was doing something wrong when I was on my own. Dennis goes above and beyond with regular check ins, breaking down the workout and how it'll help achieve my goals, and tailoring the workouts to my goals. I still have some ways to go to get to my personal fitness goal but I'm confident I'll get there with Dennis.  I've had 13 sessions with Dennis so far including the introductory package and I just purchased another package.

Diana L.

Since my very first session training with Dennis in 2016, his training methods have stuck with me to this day and his advices have helped me achieve my body goals! Before training with Dennis, I had trained with other personal trainers and one major things that has made me stick with Dennis was his extreme passion for his job and his love for seeing progress in his clients. I STRONGLY recommend him if you are searching for a genuine, effective personal trainer.  

Despite the fact that I haven't trained with Dennis in a while due to school-related issues, his training has literally been ingrained in my head, as well as all those nutritional advices that he has given, and that has really helped me continue my journey to obtain my desired results!

Finding a personal trainer that is the right fit, and will keep you constantly motivated, is no easy task. I scoured through Yelp listings (and took recommendations from friends), when looking for a trainer. After meeting with Dennis, I was pretty convinced by his realistic, yet motivating attitude. He was honest, and guaranteed he'd be cognizant of my limits, while still pushing me to meet my goals.

He offers an intro package - 3 classes - which is a great deal IMO, and allows you to see if it's a good fit. In addition to his training sessions, he also takes the time to teach about eating habits and macros. If your goal is to lose weight, and get in shape, he teaches that eating right and working out needs to be done hand in hand!

Dennis sent me an email following our first session with a list of the most commonly consumed foods, to help me understand what falls under what macros: Carbs, Fats, and Protein. Whenever I had questions or concerns, he was the one who encouraged me to text him and keep the convo going to stay on track! This is a service that def isn't offered with other trainers I've met w before.

Scheduling was a bit difficult at first, but Dennis is great about reaching out when something opens up. His schedule seems more packed these days, but if you're more flexible in hours (middle of the day), it might be easier.

All in all, still working on the fitness, but having Dennis as my coach/trainer/friend has been a life-changing asset. 10 stars! :D

This is a long overdue, well deserved review. Dennis and I used to go to the same middle school, I remember seeing him around campus. One day I found Dennis though his fitness profile on Instagram and I was really impressed by his transformation from the kid I saw years back till now. I had a specific fitness goal I was looking to achieve and wanted to find a trainer to help me with that. I looked through Instagram for other local trainers, and had the idea in mind that - the trainer's body is a reflection on their work. I looked at a few trainer's profiles, but was not satisfied with what I saw. I remember previously seeing Dennis' fitness profile on Instagram, so I went back to check out his work. The images I saw of himself and client's was what I was looking for.

I reached out to Dennis, and he was very quick to respond and very professional. He was able to schedule sometime to meet with me for a consultation the following week, and I started out with his 6 session training package. He is very sharp and knowledgeable about diet, building muscles, burning fat, the right combination of what to eat and how to workout, and more. He had one space available and was able to get me scheduled in for the next 6 weeks. He has a very organized structure for managing, connecting, and maintaining his sessions and relationships with clients, I am very impressed. He also put together a custom diet plan for me - counting macros, which was very doable.

Dennis makes sure to make the most out of the time that you have with him. I left each session with the knowledge and confidence to be able to go to the gym myself and continue with what I learned. After each session, my muscles were sore, but it's the good kind of sore, the kind you want to go back for more sore. He also makes sure that your mindset is healthy, because everything is tied together, and that is important to make sure that you are successful in all areas to be able to achieve your fitness goals. Dennis also keeps you very accountable, and I really appreciate that. Without his accountability, I wouldn't have been able to be as successful with my transformation.

I have always been working out and dieting, but I was never able to see a difference in my efforts. After working with Dennis, I lost 10 lbs in 1.5 months, get toned, and got a semi-sixpack for the first time in my life. I was so happy with what I saw that I was able to accomplish with what I learned from Dennis. I am now able to take that knowledge and bring it with me going forward.

I highly recommend working with Dennis. If he has a waitlist, I recommend that you put your name on the list, and wait to work with him. He is worth every penny!

Great trainer. Attentive and has been helping me reach my fitness goals. Covid has made working out difficult at times, but Dennis has helped me tremendously throughout the pandemic. Highly recommended!

Kevin Y.

I've been training with Dennis for 2 months and highly recommend him as a personal trainer. Dennis is the right fit if you're looking for someone knowledgeable about strength training and nutrition, detail-oriented, and very communicative.

As a slight Asian man in his 40s looking to gain muscle mass but with no experience in the gym, I wasn't sure what to expect from Dennis. Fast forward two months and I'm now extremely confident in my ability to work out on my own, properly manage my diet, and sustain this for the rest of my life. I'm also already seeing noticeable changes in muscle mass and definition.

Dennis' introductory package of 3 sessions is a low-cost way to see how he conducts a workout and understand what nutritional guidance he provides. I subsequently signed up for a 10-session package which includes workout sessions, creating daily nutrient (macro) goals, and a personalized workout routine.

On top of the challenging but fun sessions, Dennis' willingness to answer my questions (including meal choices, tracking and adjusting macros, finding a long-term gym, and refinements to the workout plan created for me) has been invaluable. There's way too much information available on the internet, and Dennis has provided me with the answers that fit my specific goals.

I can't recommend Dennis enough, especially if you're someone who's looking to establish healthy, long-term routines for your exercise and diet.

I have been training with Dennis for about 3 months and a 5 star rating just doesn't do him justice. He is definitely worth way more than that! I had a baby and gained quite a bit of "baby weight". Four years later, my son is thriving and I'm still holding on to the extra lbs. I contacted Dennis right before Covid-19 hit and shut everything down but he told me that he would keep in touch. Thankfully, he was true to his word and contacted me when the shelter in place restrictions eased up. I was thrilled when he told me that he could take me on as a client. In the short time that I've worked with Dennis, I've already noticed a difference both in how I feel and look. I meet with him weekly for one-on-one training, try to run 2 -3 days and do an at-home workout that he created for me. I have to admit that I can't always find the time to work out 4 - 5 times a week but I do try. Dennis is committed to helping me reach my fitness goals and, even if it takes a little longer, I'm fully committed, as well. Dennis is an extremely knowledgeable, competent and personable trainer and I look forward to my training sessions every week. I am truly enjoying my experience and highly recommend Dennis to anyone who is looking for a personal trainer.

I've been seeing Dennis for over a little over a year now and he's played a significant role in my weight loss journey (70+ lbs over the past 4 years). Through a combination of focused training and nutritional guidance I've never been stronger or in better physical shape in my entire life (just turned 51). My form, balance, and core are also much improved. He pushes me when I need to be pushed, but also listens, and modulates my workouts when physical limitations present themselves (again, I'm 51). :)

I've never been this close to hitting my target weight, and while they say the last few pounds are the hardest, I know with Dennis' help I will achieve my goals and more.

Over my life, I have had a few trainers.
I am confident in saying that Dennis is the best one I have had.

He genuinely seems to care and tries to tailor to your needs, instead of following a cookie-cutter plan and modifying it a little bit. He tries to encompass all facets related to your goals, not just exercise. And he will push you while making sure that you don't get hurt.

Dennis has been instrumental in helping me push back years upon years of neglect in my own physical fitness.  His fitness philosophy is perfect for a science-based person like myself.  No gimmicks, no supplements, no BS.  Just a solid program (including diet) and tons of hard work.  I feel very secure with him as my trainer because all I need to bring is a good attitude and my own will power.  The rest is taken care of.  I unequivocally recommend him as a trainer.  I still have long long long way to go but I definitely do not feel as daunted as before.  If you're ridiculously out of shape like me (to be fair, round is a shape), or you have limits based on healthcare issues, or you already are fit and want to take it to the next level, I strongly believe that you need Dennis in your corner.

As far as personality, the best way I can think of to describe him is a quiet professional.  This is perfect for me. He is friendly and approachable but won't distract you from the workout.  Dennis is very attuned to your performance and will push up right up to the line where you can't do anymore.  For instance, I thought he was just being nice setting up and taking down all the equipment.  No...that may be part of it...but by the end of our sessions, I'm just trying to stay upright so that help is deeply appreciated

I joined about 3 weeks ago with Dennis for the introductory package. I've never gotten personal training but have always heard scary story from others that their trainer is not professionally trained. I went with a consultation with Dennis about a week before my training discussing my goals and fitness level. Dennis was great at listening to me and tailoring the training program based on my fitness level while still challenges me every single session. I was sore for 3 days after our first session. Man, was I out of shape. Dennis was responsive, knowledgeable and professional. I would highly recommend him to anyone who wants to get back in shape and jump start their fitness journey. I'm continuing my sessions with Dennis and can't wait to see my result!

Jason L.

Dennis is the real deal. Seriously, look no further if you're looking for help with nutrition, fitness, or just living a healthy active lifestyle in general.

Dennis is really knowledgeable and has taught me a lot already just completing his introductory package. His whole philosophy is if I can help you learn and build good habits for the future, then he has really done his job.

I've been to other personal trainers and they have been OKAY at best but Dennis breaks it down so everything is easy to understand. He listens to what your goals are and comes up with a detailed plan to best achieve it.

He feels more like a friend than trainer to be honest, but he'll put you to work so don't get it twisted. He is very good about responding to texts and emails, almost immediately. 10/10 recommend.

David J.

Dennis is a really excellent trainer and fitness expert. He works out of Raise the Bar fitness on Judah St which has easy free parking on the street. The gym itself has good equipment and most of the time plenty of space to work.

As a trainer Dennis is extremely professional, organized and great to work with. He knows his stuff and creates unique fitness programs that includes Hit sessions, lifting and whatever is needed to customize it to meet your goals. He pushes his clients, but on top of the working out side he also incorporates his knowledge of nutrition to manage your Macros. He'll set you targets and manage what you eat - as we all know, Abs are built in the kitchen !

Dennis works from early - 5am ! And he's very popular so definitely get in touch with him directly to make it onto his client list. It suits me well as he likes to lock in the times a few weeks ahead or set regular weekly slots and he always sends a reminder text the day before.

If you want to make a change, and learn do things right in the gym then I would highly recommend Dennis!

Dennis is an excellent personal trainer. I kick started training with the 3  introduction sessions. Then I took two 24 session packages and now I will be taking the third 24 session package. This is an evidence that I am highly satisfied with his services.

Dennis is extremely flexible with his clients. He is equally committed in every client's success and keeps them motivated. He sends a text message before every session to remind them about their training session. He has great work ethics.

If you are looking for a trainer, I highly recommend joining Dennis. He is always booked, so get your name added to his list, I am confident you won't regret.

Ralpheal H.

I searched for a personal trainer to fit my personality for 3 months. Dennis isn't the trainer to instruct you to run on a treadmill or do a set of curls while he sits on his phone. He takes your health/fitness very serious. Dennis was with me every step of the way, correcting my form and giving me that extra push. He will develop a MacroDiet for you and perform weekly weigh-ins to tweak it to better fit your body type. I was blown away with his attention to detail.  

I sustained a knee injury while hiking and was unable to attend sessions. Even then Dennis would still follow up with me to see how my progression was going with physical therapy.

If you're looking for a trainer to give you special attention and genuinely care about your health/fitness success, then look no further!

Gloria C.

Dennis is an awesome trainer! This is my first time signing up for a personal trainer, and to be honest I was really intimidated at first. As soon as I met Dennis for the consultation, I knew he was the right person to help me achieve my goals.  I never thought working out was fun, but Dennis tailored each workout according to my needs and made each session something to look forward to. He encouraged me to reach my limits, but also understood that I had limits. I have an arm injury and he was able to create workouts that  strengthened it. Hopefully with more sessions it will be good as new.  Every session with Dennis is like working out with a friend. He's motivating and at the same time has great conversations during resting periods. I HIGHLY recommend Dennis to people that need that extra motivation and boost to achieve their fitness goals!

I recently finished my trial sessions with Dennis and couldn't be happier with his work ethic and professionalism. So much so that I decided to jump into the 24-session package. Foremost, he's been very diligent in communicating and responding to emails and texts, which I feel sets the tone for the rest of his service.

During our first session, he was very realistic with goal setting. He was attentive to my physical limitations and personal health goals, and took studious notes of my progress during our workouts which he uses to continually adjust and adapt the routines to  my evolving goals.

Diet has been the biggest struggle for me, and Dennis recommended a diet app to keep track of my eating habits and is very knowledgeable in offering nutritional suggestions when I ask.

During our sessions, Dennis is constantly offering clear and effective feedback for getting the most out of each exercise- a telltale sign that he's paying close attention. He makes small adjustments in posture and movements that are immediately felt, and I leave each session feeling like I got the most out of the hour.

It is clear that Dennis has a passion for his work, and his dedication to his job shows through the results that he's able to get out of you and the fact that I look forward to working out.

I found Dennis searching for the impossible scenario: a trainer who could work with my motivated but underweight 15-yr old son (kept falling off the weight charts) and me (his 55-yr old Mom).  NOT an easy dynamic. Dennis Wu graciously accepted this challenge with exactly what I was looking for - candor, experience, respect and an energetic motivation in helping us reach our goals.  So far, it's all been working on my son, but Dennis was completely flex and and very motivated to help with weight gain and strength increase.  My son is happy to see Dennis and is seeing superb results on both strength and weight gains,  Get on his wait list - Dennis is worth it!

Kim P.

I recently completed the Introductory Package which included 3 sessions with Dennis and I am very happy about the experience.  

We had a great initial consultation (complimentary) and he took the time to get to know me and my goals.  He kept in touch daily to track my diet and progress.  The workouts were demanding, included the entire body and elevated my heart rate -- nonstop for 60 minutes.  

Dennis was awesome.  He is very nice and always explained and demonstrated every exercise.  The workouts were never boring because he infused variety in every circuit.  He pushed me to do more and it led to positive results, in less than 3 weeks, I gained muscle, tightened my body and dropped 4 pounds.

Facilities: Very nice private gym, so it was not crowded.  The equipment was up-to-date and well maintained, lots of variety and options to whip you into shape.

Glen B.

This is a long overdue review.  I've been training with Dennis for more than 2 years (twice a week) and I've made great progress.  Dennis is very knowledgeable about weight training and nutrition.  He even helped me with developing training routines that I could do on my own during the week so that it complements what we were doing in our training sessions.   He also provided nutrition macros and adjusted them as I lost fat and gained muscles.  Dennis is always available to answer any questions I have about weight training or nutrition.  Some people think that just by working out with a trainer you will see significant changes.....ummm.......NOT.  You will also need to be committed to making a body transformation and workout on your own time and eat healthy wholesome foods that support your macro goals.  You didn't gain weight in just a few months so you won't lose all the fat you want to in a few months.  Sorry but that's reality.  :-)  Be patient and trust the process and you'll see the results overtime as you train with Dennis.

I would highly recommend Dennis and if he has no openings, put your name on his waitlist.  It's worth waiting for an open slot. I've had several trainers in the past and Dennis is by far the BEST!!!!

Did the intro package and planning on going back if I stay in the city! Dennis is professional, attentive, and knowledgeable about his craft. I paid money and had expectations and he met them. Would definitely recommend

I have been training with Dennis for almost a month now. My strength has increased a lot since I first started and my diet has never been better. He teaches you which foods you should and shouldn't be eating which has helped me build towards the body I want.

I didn't really know what to expect when I first started, but I'm glad that I actually started training with him. I'll leave another review in 6 months to talk about the progress that I have achieved then!

Sabrina H.

Dennis is an excellent trainer. For as long as I can remember I have always struggled with my weight, I have cycled through my fair amount of trainers and diets and nothing I ever tried worked.

I found Dennis on yelp and he seemed to have tons of great reviews, after reaching out to him, he responded within less than a day! Prior to any of the actual workout sessions, we met up for in-person conversation to talk about what I like in a trainer, my goals, and his training and diet method. Dennis is extremely knowledgeable about fitness as well as eating habits, which made me trust his method and judgement.

I started off with the 3-session starter pack and at my second session, purchased a 24-pack of sessions. Out of all the trainers I have trained with, Dennis is by the far best trainer. He not only is with you a 100% of the time, but takes the time to actually to teach you the correct forms and exercises. He also designed a personal Macro-based diet for myself, which has been pretty easy to follow. Dennis also, always texts me prior to sessions and keeps an organized file with my weight, macros, sessions, and work-out plans. He truly designs a personal fitness plan for each one of his clients and is 100% supportive of you and your goals.

He is also really fun, I know working out can get boring, but Dennis always keeps it interesting, I never come in and do the same thing. His personality as well is overall fun and encouraging, he really knows how to push his clients to succeed. It's always a good time when I go in for my session and I always leave feeling really good about myself! He's just an awesome person!

Dennis is absolutely amazing. He helped me drop over 20 pounds in under 4 months with a strict diet and workout plan. He consistently made sure that I was staying on track, and made adjustments to my plan when necessary. He truly cares about all his clients and wants to see them succeed. I definitely recommend Dennis for your personal training!

In my 3 months with Dennis I appreciate how prepared, organized and most importantly effective he is.  I have been working with trainers for over 10 years and can from my own experience say in no uncertain terms that Dennis is a phenomenal trainer.  Dennis has also helped me come to realize that work outs alone isn't going to get me where I want to go, that work outs go hand in hand with the right diet.

I am grateful to have found a trainer as dedicated, professional and passionate as he is; I am grateful that he is equally as knowledgeable on nutrition.  I highly recommend Dennis, he is simply tip top.

Dennis is a great personal trainer! He is very patient to explain all the stuff about fitness and health. I started training with Dennis for losing weight because I have been training by myself for years at gym and didn't get any good result. During the training, Dennis told me about the diet and working out route, and he trained me right target on my muscle and correct my form that I have been doing wrong for years. The result was really good, and Dennis gave me a really good foundation for fitness. Reasonable and affordable price for everyone. If you really want to get a fit body and a healthier lifestyle, Dennis is the right one.

I've worked with two other trainers in the past but Dennis is the best trainer I've ever had-! I love the fact that he is very informative of diet. I've learned so much already about what food I should be eating, avoiding and how many calories for each individual food. He is very down to earth and genuine also to push you hard so you be where you want to be fast and efficiently.

I've been working out for 15+ years and have successfully lost 20 lbs on my own after I packed on some weight from having too much fun when I first moved to SF about 10 years ago. I consider myself pretty fit and disciplined with working out but last year no matter what I ate or how much I worked out my body was not responding anymore. Thus it was time to seek professional help. I did some research online and thought Dennis would be a good match based on his experience and reasonable rates. I met Dennis about 6 months ago and have stuck with him since for good reason.

Dennis is a great personal trainer. The first thing he helped me with was adjust my diet and I like that he is constantly tailoring my diet according to my progress, energy level, and any special events (weddings, beach vacations, etc). I have tried so many different 'diets' on my own over the last 2 years (paleo, low carb/high protein, high carb/low protein, cleanses) which might work short term but over time realized they weren't sustainable. As someone who loves food Dennis has made the 'diet' portion a lot more bearable and I still have a lot of energy to workout since he focuses on 'flexible dieting'. Dennis is a great motivator during our workout sessions and has taught me that lifting heavy weights will not make me bulky or thick. Dennis is always accessible whenever I have questions and keeps me motivated by checking up on me between sessions.

Since I started training with Dennis I have received a lot of compliments on my progress and physique. Not only has Dennis taught me how to change up my workouts and diet and get closer to my goals, but i have gained a lot of confidence, which to me is invaluable.

If you are looking for a great trainer who is down-to-earth and will help you achieve your goals, I highly recommend Dennis!

Dennis is an awesome trainer! I started training with Dennis because I felt lost and didn't know what to do at the gym with so many machines, weights, options etc. He helped me create a tailored routine that made going to the gym less intimidating.

He is a great motivator, very patient, and really easy to speak to about anything fitness related. Highly recommend him for any fitness level!

I've been training with Dennis for 1.5 months and it has been great experience! I feel much stronger than when I started and I have better endurance. Dennis takes great care and focus during our sessions and makes sure to work around my previous injury. I can see myself progressing every time I go. Dennis is very helpful when it comes to nutrition planning as well and is very responsive via text when I need to check in. I'm looking forward to updating my review a few months down the line.

Ok if you're reading this you're probably interested in getting into shape. For the record I am also a  trainer and have been training for well over 7+ years. I thought I knew it all already but Dennis has definitely impressed me with his knowledge and experience.

I've known Dennis for a number of years now and I can truthfully say that he is a not only an excellent and knowledgeable trainer but a very well disciplined athlete. These are two VERY important attributes that are necessary for people to achieve fitness success.  (Nothing is more off putting than a trainer that is out of shape)

If I were researching for a trainer and ready to spend my money for their guidance, knowledge, and expertise I would ask many questions and I can assure you that Dennis is always more than happy and willing to point you in the right direction.

I'm going to try to keep this straight to the point. Dennis is not your typical trainer. He is probably one of the best trainers in the entire Bay Area. He is one that WILL actually get you to your goals. He understands and explains realistic goal setting and nutritional support to get you to your goal much quicker than you think. He also holds you accountable when it comes to your nutrition and exercise regimens. Dennis is a very humble and approachable person and will make you feel comfortable when training with him. All I can say is that I guarantee he will get you into shape and you will have fun at the same time.  You'll feel better, have more energy, and of course look great all at the same time!  I highly recommend Dennis and D-WU Fitness!

I started working with Dennis at the end of September and already feel an increase in energy and motivation. He's a no games, straight to the burn, trainer who guides you through a successful workout that will make a difference. I love how I feel like I have nothing left in me and he gets me through the session down to the last second. No time or money wasted. I look forward to continuing our sessions and getting to my goal weight. Although I truly feel I will exceed initial goals working with Dennis.

Dennis is a rare gem of a fitness trainer!!! I found him after perusing these Yelp reviews and thought that perhaps these reviews were too good to be true. True they are!!!  He is soft spoken, kind hearted and always focused on creating results optimal results.  In a short time and with his focus and inspiration and knowledge and heart I found myself significantly stronger in a short period of time. Dennis is very results oriented and he aims  to maximize the benefits of each and every workout. He is always totally professional and considerate and sensitive to the fact that i am dealing with serious health challenges.  
Surely I am really fortunate to have him on my team as he continues to play a significant role in increasing my  strengthening and stamina and overall sense of wellbeing.. How great that I can now point anyone who is seeking a personal trainer to Dennis.

I wanted to get in shape and toned for my wedding. I've been working out on and off for a while but wasn't really seeing results. I wanted to incorporate more weight training in my routine, and someone to teach me exercises and correct form so that I don't injure myself. I did the introductory 3 class package so I could see if our personality/style would match. Dennis is professional and responsive. He is flexible with my schedule as it varies week to week. He set me up with a workout routine after our first session and adjusted my macros as needed. We do daily weight check ins and having a trainer is helping me stay accountable. I'm happy with the way things are going, and just signed up for more sessions.

I just finished with the introductory package with Dennis and it has been a great experience. I have no previous background in working out but Dennis makes sure to address all my concerns and takes into consideration what I'm comfortable with and my limitations. He's very attentive & comes up with varied exercises each session so it's always challenging in a good way. He also helps with your diet. He does not waste any time and I feel like every session that we've had is well worth what I pay. I just signed up for a few more sessions with him, highly recommended!

This review is for Dennis' online coaching program. I started the program 4 weeks ago and am already seeing awesome results! I am someone who is active and works out 4-5 days a week, but I wanted to incorporate weight training into my workouts. I met Dennis in person for an initial consult and we discussed my fitness goals. Dennis is a really nice guy!  I was worried that he would be judgemental or intimidating, but I felt comfortable talking to him. He took my weight and BMI and from there he created a full weight lifting routine for me to do each week on my own. In addition to a workout routine, Dennis calculates my daily calorie and macro intake. I text him my weight each morning, and at the end of each week, physique photos. He'll make adjustments if needed. I'm currently on week 4 and loving my progress! With the online coaching program, you have to be motivated to do the workouts on your own and meal prep. But once you make it part of your daily routine, you'll love the results!

If you're looking for an approachable and knowledgeable trainer, Dennis is your man ! I was looking for a trainer who would 1. Help me lose weight 2. Teach me how to properly use equipment and proper form 3. Be non-intimidating. Dennis has helped with all of these. He is friendly, yet extremely approachable . He knows when you can workout harder or when you need a break and caters every session towards your progress. He will "assign" you to certain allotment of macros to aid your fitness goals. He doesn't believe in supplements , but has a realistic approach to weight loss and offers many suggestions for what to eat. His workouts change every single session and leave you sweating and sore.

Dennis is a very dedicated trainer. This is my second time training with him. I was felling so lost put some extra pounds on and back training with him was the best for me. This is my 5th week back. The results is amazing.  The tips for nutrition is 100% efficient.  He has so much knowledge that everyday is a new challenge. Highly recommend.

It's been a rather very long time since I've seriously worked out. Wanting to get back into a gym routine along with some help working on form and other various things, I decided that a personal trainer would be the best fit for me as all of this can be rather very intimidating initially. Finding a personal trainer that was the right fit for me was the next step, but thankfully that turned out to be much easier than I thought! I ran across Dennis' Yelp page by chance and decided that his location would be the most convenient with me with plenty of parking (also the fact that he and I have the same name) and decided to give him a try. I have spent almost a month or so now with Dennis twice a week now and can say that I truly recommend him to the fullest! Dennis is very personable, friendly, and is extremely knowledgeable! He listened to my goals, was very accommodating towards them, and immediately set me up on a step-by-step process of slowly helping me achieve them. Although it's only been a month in, I am already seeing very good results and I plan on sticking with him as my trainer for the long run. No gimmicks, no "magic diet", no nonsense stuff, just a simple yet effective plan to follow. Dennis may be more expensive than other trainers, but is more than worth what you pay for!

I trained with Dennis at 24, several years ago, and found him to be a very focused and compassionate trainer. When he went out on his own, unfortunately I didn't follow. Fast forward to January of this year, I decided I needed that little push, to get moving again at 63. The experience has been great. He pushes me just enough, but is certainly in tune with my limitations. Young , old or in between, train with Dennis, he will not disappoint.

Dennis is an amazing trainer and has helped my son lose over 15 pounds!! I heard about him through my friend and reached out to him.  My son need some serious help since he lives in two households and it's hard to keep track of his exercise or eating habits. Dennis gave him the guidance he needed. My son is shy but found it easy to work with him. Dennis was very compassionate when he heard a mom's cry for help and gave him a spot in his busy schedule. Thanks Dennis!

I'm not at all surprised that Dennis has 5 stars across the board.

As a female never having trained with a male trainer, I was nervous before setting up an initial session with him. But during our first meeting, I found him to be personable, honest, and knowledgeable about what he does.

In the 6+ months I've been working with him, I've been able to lift more than I thought I could do on my own (which was one of my major goals) in addition to losing a bit of fat and gaining muscle. Even though he and I both know that I could be more consistent with my macros, he never makes me feel guilty for being off track. His training sessions can be pretty tough, but I look forward to them because I enjoy his style of training and I feel like I'm training with a friend and not just a trainer. He is able to push me just out of my comfort zone and modify as needed.

I highly recommend Dennis if you want help with getting results (losing fat/gaining muscle & strength) with a realistic approach.

I like working out with Dennis because he listens very well to my concerns and provides such honest feedback.

He uses his own experience which includes his struggles and outcomes as a natural bodybuilder to motivate me to be consistent with my own health goals.

He is also accessible and flexible which is very important to me as a busy woman.

Overall, I admire his work ethic. He understands very well the professional dynamic between a personal trainer and his client so he is always able to give me the best workout during our sessions.

I'm glad that I found a trainer like him thru yelp. :)

Before training with Dennis, I have been going to the gym on and off only to get dismal results / no noticeable difference. I'm a hard-gainer, have extraordinarily high metabolism, weigh only 146 lbs and almost 6 ft tall. Sometimes I try to follow the workout routine on youtube, but didnt follow through consistently. Things began to change when I decided to train with Dennis Wu.

For one thing, Dennis is very passionate in helping his clients achieve their goals. He put a lot of emphasis on my diets / macro, and set a goal to gain roughly 2.5 lbs a week. It was hard in the beginning, as I didnt use to eat that much, and with the help of the macro-tracking app, I am able to bump up my protein drastically. Today I weigh 154 lbs and still on-going. I never would have imagined that I can actually gain. He is always ready to answer your question about food, how often you eat, and how much you eat. I find this to be very important.

We workout roughly twice a week; each session is an hour long. Dennis is highly flexible, and would try to accommodate and work with the client's schedule. The first thing I learn is you should always train different part of your muscle via compound exercise, for instance, you want to bench press, then do a lat pull down, then do the rowing, the back squat, and so on. He switched up the intensity, and teaches me different techniques and workout regimes. He also emphasized a lot on the legs muscle with lunges etc, and not just the upper body.

Thanks to Dennis, I can now see noticeable difference! will update again in a few weeks!

The hardest part about trying to get active is starting - how and where does one even start? I'm very thankful that I found Dennis to help me with this. In the beginning, I was quite nervous since I went in having no prior experience in a gym setting. Dennis was very understanding about this and made sure to clearly explain/demonstrate every exercise he had me do. He genuinely cares about my health goals and gives honest feedback whenever I have any questions or concerns.

Two years ago, I wanted to hire a personal trainer and my friend recommended Dennis Wu. Dennis wasn't just a personal trainer but a friend to me. He've taught me how to count macros, meal prep, different workout routines and the most important thing was not to give up. He was very professional and a humble person. Without him, I wouldn't be the person I am today. So I highly recommend Dennis because he will definitely get you where you want to be!!

Dennis is so fun to workout with. I started out not knowing how to do anything correctly. My squatting and lifting postures were all wrong, i was skipping certain foods because i thought it would cause weight gain, and i just hated working out in general. But once dennis started training me, he pushed me past what i thought were my limits every time we had a session. And made me realize my body could handle a lot more than I thought. he also will text me reminders on my meal plans and structure one specifically for my body and weight. He's such an amazing trainer and friend :) definitely try him out

Marlene C.

Where do I even start. If you need a trainer, look no further. Dennis is very knowledgeable and will push you to your limits. I had been going to the gym and working out for a while and my body had begun to plateau. I wasn't really seeing changes anymore and the workouts I was doing started becoming monotonous. I could try doing it on my own, but I didn't know what I should do, this was when I asked Dennis to train me. The workouts he had me do got me sweating in less than 10 mins. It was a mix of weight lifting and plyo. He made sure the workouts targeted the areas I wanted to work on, but we're also fun so I wouldn't get bored.  If you want to feel good and look good, Dennis will help you get there!

Dennis is my first personal trainer and he is great! He knows how to push you hard but is always considerate that he isn't pushing you overboard. He is cool, calm, collected and is always available to answer questions about health and wellness. He is also super flexible with my changing schedule which is a major ++++ I highly recommend him especially if you are a newbie to the personal fitness game.

Dennis is by far the best!! You will not be disappointed. Getting in shape is not fun or easy, but he really changes all that with his support and motivation. He is much more than just a trainer, but a friend that will help you reach your goals and strive for future goals! I was new to working out and had a bunch of questions, but he was super patient and answered everything little one. You can tell he is very passionate about his work. And my favorite part is I don't have to go on some crazy diet! He was able to help me customize my diet so I could still eat what I love and still reach my goals. He really knows his stuff!! Thank you, Dennis!!

I met Dennis a while back, started training, and making progress towards my goals. The amount of knowledge, on top of his experience, plus how humble he is, makes it a great time training with D-Wu. Dennis put me through one of his exclusive training regiments which included: one on one training, how to count macros, and weekly check ins. Since our paths have crossed, Dennis takes time to adjust your training schedule, adjust your macros, in order to progress forward towards your goals. I can bend your ear on how great D-Wu fitness is, but the bottom line is: I've been training for years and D-Wu fitness is LEGIT! Dennis has this down to a science. If you want to make gains, tighten up, or maintain, Dennis Wu will help achieve your fitness goals.

I've been trained by Dennis for about three months and I can say that he has been very patient and thorough with my training program. Frequent diet and weight check-ins, control over the form, and encouragement helped me get on the right track with my fitness goals. I would recommend Dennis to anyone who wishes to improve his/her physique.

I've been training with Dennis on and off for a few years now and he is great! He is the best motivator and I feel very comfortable with him. He will set realistic goals for you and help you achieve them. I have been slacking at the gym and needed an extra push and he was definitely the right person to call. Being back at the gym for only a month now I've already seen great changes with my body. If you need a honest, knowledgable personal trainer, I really recommend you give him a call !

Dennis is seriously as good as personal fitness trainers can get! Three things I like the most about Dennis -- his dedication, sincerity and depth of knowledge (what more can you ask for from your trainer!). He is always on time, never cancelled on me (yes, I've had prior experience of trainers cancelling on me 30 minutes before the session!), he diligently takes notes of what exercises I am doing, and keeps track of my progress. I am no expert on fitness training but if I compare Dennis with other trainers I have had before, he has a wealth of knowledge. He calibrates my food intake in terms of macros according to my weight, fat percentage and exercises I do. He also makes sure that I work on all parts of my body. Above all, he gives undivided attention during those 60 minutes I train with him and he also makes sure I get every cent's worth during those 60 minutes. It's been two months since I started to train with him and I am already seeing results. I think Dennis is a full package and it's rare to come across such trainers these days.

So I've been to the gym before and didn't really know what I was doing. I was always going on and off and doing a lot of research with meal prep and exercise routines and did not see any results. I decided to look up personal trainers and stumbled upon Denis. I looked up his website read the reviews and got a lot of positive feedback and on Yelp as well. So I decided to do the introductory package which is three sessions. I emailed him first before anything and he set up a time and day to meet up. When I first met him he was straight forward and ready to do work. He gave me a lot of advice and answered whatever questions I had. Denis really knew what he was talking about and explained everything to make me understand. So if your looking for a trainer he is the go to guy.
