X-Zact Fitness: Opinions

Fantastic experience: Zack and all the coaches were incredible!! I joined the 6-week challenge and I not only reached my goal, I exceeded it. X-Zact Fitness provided nutrition plans & nutrition check-ins and accountability coaches. We had group workouts 3 times a week. The coaches were really supportive, high energy, and took the time to show us correct form and movement. Clean gym, easy parking, and positive atmosphere. I would definitely recommend X-Zact Fitness. Thank you Team!
Fantastic experience: This place is the real deal. I have experienced tremendous improvement with my weight, strength, and stamina since joining and doing the group fitness classes. Amy, Ciera, and Cassie plan well thought-out sessions and are wonderful motivators. De’Vin is an expert on everything nutrition. Zack is responsive to questions and concerns I may have. Honestly, I am in the best shape of my life and X-Zact Fitness is a huge reason!
Fantastic experience: Excellent coaches, highly effective nutrition advice, great group workouts, all around sick vibe
Fantastic experience: Awesome place to work out! Challenging sessions, great coaches and the people that go there have all been just as great. The coaches will help you with everything from basic form up to nutrition coaching and everything in between. Not one of them will ever belittle or make you feel uncomfortable for asking a question or asking for help. Seriously, this gym is awesome!!
Fantastic experience: This is the absolute best gym in the Bay Area — best value, great culture, and the best trainers. I went through a couple trainers in SF and East Bay before I arrived here and the prices elsewhere were astronomical, and I felt like not much more was gained outside the basic session. Here, my trainer Cassie is the absolute best - she puts so much energy into our sessions and my goals are genuinely prioritized. It has been game changing for me to have a trainer who is tracking my progress, pushing me at the right moments and envisioning the next best steps. Not only is the training great, but it’s at the most reasonable cost I’ve found and the non-membership based programs and classes are so affordable and perfect for supplementing your sessions. I’m a lifer here for sure.
Fantastic experience: I have been working out with Cassie since April and have loved every single session! She is fantastic! A ball of energy with an amazing attitude! She is supportive and motivating! She has made working out fun for me and turned it into a habit. The gym is nice, very clean and definitely feels like a private training space. Also, every single person I have met at this gym has been wonderful! It has definitely been a pleasure training here. Schedule a session and you will see what I mean!
Fantastic experience: Hands down the best gym in the area! I have been going to this gym for the last 3 months and have done Personal Training with De'Vin and Lizette + group classes with Zack, Cassie and De'Vin. Everyone is friendly and so helpful. Most importantly they make sure your form is correct so as to avoid injuries. The first time I inquired about the gym, Zack called me and walked me through the different options and that really helped me determine which classes I needed to join. My first class was with De'Vin and he called the next day to check on me to see how I was doing. He gave me ideas on what stretches I needed to focus on to relieve soreness. I've been doing Personal Training with De'Vin for 2 months now with a mix of group classes and I can see/feel a big difference in my strength and overall body conditioning. If you are looking for a gym in the area, give them a call and try it out. I can assure you that anyone you work with will make you feel welcome and help you attain your goals. You will love it!
Fantastic experience: I love this place! What a clean gym!!!! Positive, friendly environment-so grateful. Easy parking as well. De’Vin took time to hear about my old injuries. He is thoughtful and very observant with my movements, always making sure I’m doing it correctly. He challenges me and yet has a gentle demeanor. What a great trainer he is! I am so glad I took an extra step to have nutrition meetings with him. I’ve learn things that truly benefits my eating habits as I move forward. Cassie substituted for two of my sessions and took good care of me. Thank you so much!!
Fantastic experience: The instructors were awesome!!! Very helpful and motivating!!!
Fantastic experience: I came to X-Zact Fitness to work with De'Vin after my chiropractor recommended him. I needed some help learning how to weight train after a spinal injury, and am so happy I ended up here! De'Vin was super patient and attentive in always making sure my form was correct, and really took the time needed to make sure that I was training properly to protect my prior injury and also get stronger. I had no prior weight training experience and left after my 12 weeks totally hooked! I'll definitely keep up my routine. Overall I found the gym to be a positive environment that was judgement free, and easy to be in. I really enjoyed chatting with everyone I met, and always felt comfortable. Totally recommend checking out De'Vin, and this local fitness gem, if you're looking for one-on-one personal training instruction :)
Fantastic experience: With so many options out there for personal training and nutrition coaching, I couldn’t be happier that I chose X-Zact fitness. They’re knowledgeable, made me feel comfortable from day 1, and they were the accountability I needed to help me reach my goals. 10/10 will recommend them to everyone I know.
Fantastic experience: If you are seeking personalized fitness training with highly knowledgeable trainers, this is the place. I am seeing great results after 2 months. I appreciate the flexibility they have with working around injuries and other limitations while helping me work towards my goals.
Fantastic experience: I have been training with Cassie twice a week since December 2021. She is an amazing trainer, so innovative and positive. I have seen such a difference in myself, mentally and physically and really appreciate how she pushes me to be my best self. I look forward to our workouts together every week! The staff at X-Zac fitness are wonderful. If you are in the market for a trainer that will help you get back to exercising, I highly recommend Cassie!
Fantastic experience: De’Vin Thompson is a very caring trainer. Plus he’s fun to chat with. Have to say I’m in terrible shape and he has helped me so much already. I would highly recommend De’Vin.
Fantastic experience: I've been working with Cassie for over a month. She is great at what she does. Her professionalism and enthusiasm makes working out enjoyable! Every workout is different and tailored to fit my needs. I've had several personal trainers throughout the years and Cassie is by far one of the best! Would strongly recommend!!
Fantastic experience: Love the womens bootcamp classes! Amy is an amazing coach - so motivating and a great workout!
Fantastic experience: I have tried many gyms, studious, classes etc even at home exercise programs .. BUT there is something about X-ZacT fitness and this ladies bootcamp that is soul healing. Amy is an excellent coach, upbeat, positive, kind and oh so very human! We laugh, scream, we hug and push through many burpees and squats together with excitement! It honestly never felt this good to hurt so bad! Thank you ! Warmly, Dajana
Fantastic experience: Positive: Communication , Professionalism , Quality All the coaches are great and have high energy. They really take the time to include modifications. These are high cardio class. I enjoyed that they utilized indoors and outdoors as well. I am a beginner with fitness and had no troubles keeping up.
Fantastic experience: My experience with X-Zact Fitness has been nothing but wonderful. I came in with zero experience or knowledge about working out and developing better/healthier eating habits but Zack and De’Vin were so quick to demonstrate support and have shared so much knowledge with me. I never thought I would be excited to get my workout in. I came in with so many aches/tight areas and not having a clue about what was causing them or what to do about them and surely just after 2 weeks, I feel like a new person. Although, I am constantly pushed and motivated to go harder, they never make me feel like I should be ashamed for not being able to meet my goal and instead work with me to get to that point. Not only have I lost 5 pounds already, but I feel like I have gained so much knowledge on how to work my muscles and relieve tension. I wake up feeling energized and ready to go everyday thanks to their guidance and tips. If you are looking for training with a purpose, this is your place. I look forward to continue working with them.
Fantastic experience: X-Zact Fitness is amazing, I love the gym and working there one-on-one with my personal trainer, Amy, who is amazing. Amy has been incredibly supportive and gives a great workout. X-Zact Fitness offers me the nutritional support and weight training at an incredible value. Zack has been very attentive and supportive in helping me reach a healthy nutritional diet I need. I’d recommend anyone work here, it’s so worth it and your body will thank you.
Fantastic experience: Positive: Communication , Professionalism , Quality De'Vin has been amazing! He provides me valuable feedback on a regular basis, and has been with me every step of my weight loss journey. De'Vin and Zac are knowledgable, caring and personalize the program to fit within my lifestyle and needs and still help maximize results. So happy I found X-Zact Fitness.
Fantastic experience: I love the individualized workouts I get from my trainers at X-Zack. I’m 65 and haven’t worked out like this in a long time … so I think I’m a bit of a challenge. De’Vin even spoke to my chiropractor so that we could begin strengthening the right areas, and is careful that I’m doing things correctly so that I don’t strain anything. Amy is very quick to adapt exercises that I can’t quite do yet and always makes me feel like I’m really accomplishing something when I can move on to the next level. They are both helping me to feel stronger every week.
Fantastic experience: After the closing of the gyms due to the virus. I was trying hard to keep exercising and stay motivated.. it was an uphill battle! I decided to have personal training in the house. A decision I am so happy I made. Zack is very personable and efficient, he listens professionally to your needs and brings all the necessary equipment to the backyard and creates a little gym where I do everything I used to do in the bigger gym without missing a beat. He disinfects all the equipment before and after the session and very thorough in tweaking every movement so you don’t injure yourself. Thank you Zack for making me bounce back to work out and feel much better and stronger.
Fantastic experience: Positive: Communication , Professionalism , Quality I have been working with De'Vin for a number of months now 2x per week. my strength and endurance have improved and I feel great. I feel attention was paid to my age and conditioning at the start and a systematic approach to build me up has been employed. I would highly recommend X-Zact Fitness.
Fantastic experience: Positive: Communication , Professionalism , Quality It’s been great having Zack work with us. He is very attentive to our needs, creating workouts that we feel successful doing and challenging us a little more each time. We look forward to our sessions. Thank you, Zack!
Fantastic experience: De’Vin I’d a great trainer! He is very organized and communicates extremely well. He is clear about our goals and is always attentive to any possible pain areas. We do not waste any time yet he is always open to a “mask break”. It took me a couple of weeks to get back into the training routine and he was very patient with that time. I feel we are making great progress. I have nothing but compliments. Thank you!!
Fantastic experience: Positive: Communication , Professionalism , Quality This is an excellent gym for boot camps and personal training. The trainers are very nice and make a new person feel very welcome. The boot camps are tough but boy they can whip you into shape. I love my trainer Amy. She always mixes up the workouts and is mindful of limitations and super sweet. I highly recommend this gym!
Fantastic experience: If you're looking for a fitness coach who combines personalized workouts and great communication, Zack is your guy! I look forward to continuing workouts with Zack in order to reach my fitness goals and overcome the common obstacles to being consistent. Zack's enthusiasm, experience, and knowledge are a motivational and confidence booster. If you want to get stronger, more fit, and more energy, I highly recommend Zack to help you power through your goals!
Fantastic experience: So happy with my choice to sign up with X-Zact Fitness! Zack is a fantastic fitness instructor. He motivates and guides using the best balance of support, encouragement, and proper technique. I look forward to my workouts with Zack and have already seen weight and fat loss with muscle increase in just my first month. Working with him has been a huge blessing for me, especially during "COVID" times. He makes it work and has helped me start reaching my physical goals! I also have want to give a huge shout-out to De'Vin who is phenomenal! He keeps me accountable, teaches and advises on the best techniques (my knees and shoulders thank him!), and is very motivational. De'Vin has put a lot of work and effort into my program, and it has allowed me to start reaching my goals (again, I'm only one month in and seeing results!). A little background on me....I am a former US Marine and being out for 5+ years both Zack and De'Vin have helped me start getting back to my "lean and green days." I can't wait to see my full results at the end of my 3 month plan as I fully expect the results to speak volumes for our goals together. If you are looking for the best support to help you move forward in your fitness/health future, Zack and De'Vin are fantastic!
Fantastic experience: Great coach and trainer! Zack tailors workouts to your needs and wants. He takes his time getting to know you and your fitness goals. Highly recommend him if you are looking to not only get into shape, but changing your lifestyle for the better!
Fantastic experience: Over the past few months I have been using Zachary as my fitness trainer. I have noticed strength in my quads and hamstrings which helped protect my injured knee. Increased muscle tone, and flexibility. Thank you Zachary for encouraging me to continue on a daily program of taking care of myself. Ann

Fantastic experience: Hi! My name is Nikki! I lost 13lbs during the month I worked with Zack!

Fantastic experience: There’s a reason Zack has all 5 stars. I couldn’t ask for a better coach. He’s motivational, without being pushy. Always upbeat and eager to help. Just an all around great guy. I didn’t expect to enjoy exercise/weight lifting as much as I do. Zack has really helped make the process enjoyable for me. Even though I’m new to lifting, I’m already seeing measurable results. I love having a coach and feeling supported throughout the entire process. It’s really great to have someone in my corner rooting for my success. I would definitely recommend X-Zact Fitness.
Fantastic experience: I’ve been working with Zack for over 90 days now, and I feel amazing. My resistance and strength have improved significantly, and I feel a lot healthier. The workouts are always different and fun, and I always look forward to hear what he came up with for today’s workout. Group bootcamps are great too, and very challenging. He is extremely professional, cares about his clients, and is there to support you every step of the way. I feel like I couldn’t have found a better partner for my fitness journey.
Fantastic experience: I have been seeing Zack on a regular basis for almost 4 years. Zack is always ready to go, with a complete workout plan that is frequently updated so the workouts never get boring.

Zack caters to each individuals specific wants and needs. I highly recommend X-Zact Fitness, it will change your life in a positive manner!

They genuinely want to help me cut fat, gain muscle and feel better about myself.
Fantastic experience: I weighed 387 when I started working with Zack. I am now 280 moving down the scale while moving forward in life, strength and self-worth.

Cannot recommend enough for those looking for an inspiring, down-to-earth personal trainer.

I can say that since I have started working out with him, I have gained more muscle throughout my body. It is exciting to watch myself grow along with him getting excited for me. He is very knowledgeable, and is always respectful of your limitations. He never makes you go harder than you can, but he will always push you to your full potential.

I highly recommend Zack for whatever level of excersize you are looking for.
