Ive been working with Sean at this location for over a year. I can’t describe how thankful I am for his flexibility to work around my hectic work schedule and make time for me ALWAYS! On top of being a top notch fitness professional, I also love that he is willing to try new workout styles (i.e. we picked up boxing at the end of our sessions) to cater the workout to my wants and mood of the day! I swear it’s like he’s a mind reader and can tell what type of workout you truly exactly need that day! It took me several tries to find “the ONE” but Sean is it!!! :) I also enjoy the studio vibe at this location. The other trainers are just as amazing too and super friendly. It creates for such an inclusive, fun, and positive environment for all customers.

I feel like I hit the jackpot with Coach Sean Cruz and foundation fitness! I’ve always been very self conscious in the gym so I was looking for an option with a professional trainer at a gym that wasn’t where people go to be a scoped (I used to train at Equinox). Coach Cruz works at foundation fitness in Ashburn and he trains me and a friend at the same time in their private studio. It’s a great set up that I look forward to going to two times a week since I can visit with the friend I train with and coach Cruz. Coach Cruz is very professional and knowledgeable when it comes to training. He is also very personable and friendly. He is very good at listening to your feedback and adjusting based on your input. He is even willing to play the music you like during your workout (extra bonus). He’s always on time and has never cancelled. He is very flexible with me on time as I have had to miss appointments and he is always happy to help me reschedule them. I can’t say enough good things about coach Cruz and foundation fitness. So glad I found him!

I have been working out at Foundation Fitness of Ashburn before it was Foundation Fitness! I currently work out with Kevin. He is a very attentive trainer. He pays attention to a client's training goals, physical condition and special needs (like injuries or weak body parts). I appreciate his knowledge of the human body and muscle system. He has helped me strengthen a gimpy shoulder and increase my strength at the same time. He is quite flexible in scheduling, which is important to me as I travel some for work. And he pays attention to my desire to train without other people in the gym because of the coronavirus. Kevin pays personal attention to the gym being clean and sanitized, which I appreciate. Overall, I highly recommend Foundation Fitness of Ashburn and Kevin.

I worked with Kevin for more than half year . Kevin was a great coach, he definitely knows his stuff and he was capable of applying different training methodology to the right person. The studio is one of the cleanest gym I had ever seen. It was a great experience overall. Will recommend to my friends.

If you are serious about physical health, I recommend Sean and Foundation Fitness of Ashburn. I worked with Sean for six months and learned a lot. Trainers focus on overall fitness, not just lifting weights. They work with you on your diet, exercise, mobility, etc. Before joining Foundation Fitness, I used to work out five days a week, doing the push pull routines and I was getting mediocre results. After joining foundation fitness, I worked out 2-3 days a week and could see the results in just three months. We mainly focused on compound movements, and Sean monitored my diet (primarily carb and protein intakes). Sean educated me about concepts like one rep max and what to eat/when to eat. What I liked: - Professional and friendly staff - Flexible around your schedule - Great facility/equipment

I’ve been active my whole life, but I felt like I turned 30 and wasn’t making progress anymore. Kevin knew how to help right away by hooking me up with Maxine. Along with some nutrition guidance, Maxine was able to help me lose 20 pounds of fat in 4 months! The workouts have consistently been challenging but fun, and I’m always looking forward to the next one!

I absolutely LOVE working out here! I used to go to a big gym but after the pandemic I just didn't feel safe in that environment. Everything is so clean and well organized in this studio. You can tell they actually care about your health and well-being. It's also been wonderful to work with such a knowledgeable trainer. I have a handful of random health issues and Kevin does such an amazing job tailoring my workouts around that. He pushes me to do my best 💪 I've met and worked with a few other trainers there as well and they're all fantastic. Working out here has definitely taken my fitness to the next level. I'm so much stronger than when I started. I cannot recommend this place enough!

Kevin has been working with me for a while now, he always is ready for whatever i bring that day. If I'm having a bad day he pushes me through it, if my shoulder starts to hurt he adjusts the exercise to suit my needs, and best of all makes me always want to go every morning by being a joy to train under! I highly recommend this place to anyone who wants to have a great workout with fantastic trainers

I highly recommend Kevin at Foundation Fitness to anyone who wants to get in shape. He is knowledgeable and helpful, and will get you out of your comfort zone. He listens and helps you achieve your goals by making the workouts enjoyable with humor and conversation. You will be sore afterwards, but it will all be worth it!

I’ve been working with a personal trainer at Foundation Fitness and seeing great results! In the past, trainers have pushed me too hard and I dreaded going and felt very sore the next day. Sessions with Kevin at FF are at a great pace for me where I’m getting results and enjoying it and I’m keeping it up! Highly recommend.

I have been working with Sean for almost a year now. 10/10 would recommend Sean and Foundation Fitness to anyone looking to make life changes. Sean is very accommodating, knowledgeable about fitness and nutrition, and will customize a program that works best for you. This is the first time I have ever used a personal trainer to help me with my fitness goals and I couldn’t be more satisfied.

If I could rate 5+ stars I would. I worked out with Kevin for a little under a year. My original plan was just 6 months, however with the knowledge and guidance Kevin was giving me, 6 months seemed too short. I started off as someone who had never weight trained and knew very minimal about form and how to lift weights. Kevin was always very patient with me, taught me proper form, and as a result he gave me confidence that I wouldn’t have had without Foundation Fitness. After moving and no longer in the Ashburn area, I feel confident about what I’m doing in the gym thanks to Kevin and will continue to use those skills for years and years to come!!

My Husband and I worked with Kevin for about 10 months leading up to our wedding. Kevin is knowledgeable, helpful, and (above all) entertaining. He listened to our goals and brought a multi-level approach to achieving them through fitness and nutrition. We loved working with Kevin and were so sad to leave, but we had the best experience working with Kevin (and Shaun)!!

I want to take a moment a share how grateful I am, that I met coach Kevin and coach Maxine, and for the impact that they have had on my life. Coach Maxine has been more than just a trainer to me; she has been a source of motivation and inspiration. Her positive attitude and energy have kept me going. Her guidance has been instrumental in helping me reach levels of strength and endurance that I never thought possible. Kevin's nutritional advice have helped me not only reach my physical goals but also improve my overall health and well-being. Thank you!

Kevin has been wonderful as a trainer and teacher. I have been learning how to activate/reactivate muscles that haven't been engaged in years. He is knowledgeable in all areas of body movement and I've also learned nutrition tips from him. I would definitely recommend Foundation Fitness.

Having started working with Kevin in late October 2022 I have already noticed increased muscle control and definition. He is motivating educating and encouraging. I do have to warn you if you asked him any questions about his strongman competitions he will show you the video.

I’ve been working with Kevin for about half a year and before coming to Foundation Fitness, I never imagined how strong I would become! Kevin is an amazing trainer who knows how to customize your workout based on your goals and body’s needs. He’s knowledgeable in how bodies work/move and will adjust your form accordingly. I also appreciate the care that’s put into the gym to keep it clean.

I meet Kevin on Easter Sunday and discussed my fitness journey, my goals for the future. Kevin was fantastic and walked me thru the 6week trial program. I am glad I made the decision. I have had great success and feel like I made a friend. I decided to make a 6month commitment and I continue to see and feel the results.

I had a wonderful experience during each training session with coach Kevin and coach Sean. They are very knowledgeable and flexible. I highly recommend Foundation Fitness.
