Capstone’s Lacrosse training program has been the perfect way for our son to build his lax skills. Chad is a patient, thoughtful and encouraging coach. He brings a lot of energy every night and has a great connection with the kids. Definitely recommend this for kids that are looking to challenge themselves in the sport

My 15 year old is a soccer player on one of the top soccer teams in the area. We started Capstone about a year ago and I have seen significant improvement in his ability to change direction and accelerate. He also improved his overall strength and can now do multiple pull ups and has recently been able to do a muscle up. We have been so impressed with his progress that we recently started our 10 year old in the program.

KJ has worked with my 14 YO son for the past 18 months and has guided him in a total physical transformation. KJ has also developed my son’s on-field confidence and game-time decision making.

In all interactions the long-term health and safety of the athlete is always at the forefront. I highly recommend KJ for motivated and dedicated young athletes who are ready to take their fitness and performance to the next level.

The performance training program at Capstone is excellent. The coaches are highly intelligent and very knowledgeable on how to train the young athletes.

My 10 year daughter has improved significantly in her running mechanics, speed and strength, which is very noticeable on the soccer field. Several parents have noticed the difference, and asked me what she is doing to improve.

If you are looking for a safe/supportive/intelligent program to help your young athlete improve in their overall performance then I highly suggest you reach out to the coaches at the Chantilly facility. Capstone is an excellent place to help them improve and achieve their goals.

I can’t give enough praise to KJ and the Capstone staff. Not only have I noticed significant improvements to my speed and performance, I am also excited for each training session. KJ is incredibly patient, caring, and genuinely passionate about each player he coaches. He also possesses an unparalleled amount of knowledge and experience. I would recommend him to anyone, regardless of age, purpose for training, or experience.

I highly recommend Capstone Chantilly to anyone looking for strength/agility training and injury prevention for their child. My 15 year old daughter, who plays competitive soccer, has been training in Chantilly with KJ since June and feels that the training has helped her with her performance on the field. We have referred multiple friends to KJ/Capstone and they all similarly had a great experience. KJ has been fantastic in working with us to address my daughter's specific training needs and also to help us make up missed trainings. Highly recommend!

Training with KJ here has enhanced my performance on the field to a level I would have never been able to achieve otherwise! I’ve trained with him for multiple years and have seen excellent results in speed, agility, physical strength and mental strength to be able to push myself past my limits!

I have been working with Coach KJ for a few years now. He has been an incredible trainer, mentor, and just friend to me. He has drastically improved my physical and mental ability which has allowed me to reach the professional level of soccer in Europe. He helps me with programs while I’m abroad and whenever I get back we get straight to work, preparing me for the next season. I have gone 4 seasons without missing a single training, match, or opportunity to play and I attribute that to the lessons and strength I have developed from working with him.

I’ve trained with Kevin for multiple years… I first knew he was legit when I got stronger in 2 months of training with him compared to over a year of training by myself. Everyone goes over and beyond to support each athlete in both their sport and as people. Has made me the athlete and person I am today! Forever thankful 🙌

I cannot say enough good things about Capstone Performance at Chantilly! As a college basketball player who has suffered various knee injuries followed by surgeries, I needed a training program that promoted my health and optimized performance rather than just working out hard and getting tired. Coach KJ was the first private trainer I ever witnessed programming in such a way that I got stronger, faster, and stayed healthy and pain free during my training duration with him. I reached new levels of strength and speed I didn’t know was possible! If it wasn’t for him and Capstone, I would not have finished my senior season healthy the way I did.

We were totally blown away with KJ’s expertise and attention to details right from day one. Within a month of training we could see that our sons posture and runnjng form were drastically improved. He is now much stronger on the ball and has more confidence with his strength on the field.

I am a former college athlete and have been trying my best to do adult training in order to stay fit & have an all around healthy lifestyle. KJ has been able to help me achieve my health goals & continue to support me through this journey. I would highly recommend KJ & his team to anyone looking for a little assistance and help you achieve any goals you might have for your fitness or healthy lifestyle.
