Our Story #CommunitySupportedFitness

Our Story begins with a random, free Saturday morning bodyweight bootcamp at a Bethesda, MD elementary school, and has evolved into a comprehensive, yet simple, idea of #CommunitySupportedFitness.

We wanted to provide a convenient and supportive fitness environment to raise the level of health and longevity for Bethesda, MD. From our humble beginning outdoors with a small bootcamp to an athlete development center to a Record-Setting Powerlifting Club. We continue to evolve with the goal of giving back to the community.

If you are looking for Greatness, 495 Strength & Performance is your guide.

Coach JJ

I have always been an athlete. I love competition. From Little League Baseball to Friday Night Lights in High School, the city-wide marathons of my ’20s, and USA Powerlifting and USA Weightlifting in my ’30s.

I am not a personal trainer. I am a strength coach.

In our training, we develop personal goals, a game plan, and then execute it. I modify workouts on the spot to meet the athlete’s needs in an age-appropriate manner. Our group sessions include learning barbell movements, bodyweight and resistance training, speed, agility, and coordination. We combine strength with speed and coordination to produce athlete’s coaches love.

JJ is an excellent trainer who really focuses on so much more than just building strength. Our son has worked with him for almost a year. JJ hasn’t just told him what to lift, he has taught him how to lift. With proper form and progression, my son a gained a ton of strength safely, no injuries. And, between his consistent improvement in strength and the camaraderie in the gym, my son’s confidence has soared. He was like a different kid on the football field this year. Thanks, JJ!

From Google 5/31/20:
I started training with Coach Jonathan from 495 Strength and Performance a month ago and I already am and feel stronger. I was able to go from doing around 15 chin-ups to 21. My 40yard dash time went from 5.6 to 5.3. My bench press, deadlift and squat also skyrocketed. I’m putting on mass thanks to him. He’s very professional, dedicated and he has experience.
Thanking you in strength 495 ! 💪🏽💪🏽

Coach JJ has been amazing. He has worked with our 12 y/o for overall fitness improvement and to prepare for the upcoming basketball season. We have seen marked improvements and my son looks forward to attending his training sessions. Coach JJ’s plan and meal plan discussions have definitely been on time and on target.

From Google: 1/15/20
Coach JJ is the only trainer that has been able to keep me motivated and engaged for more than a few months. JJ has been my coach for almost 2 years in with his bootcamp ( 3 days a week) and strength training. I have seen real results in strength, energy and general well-being. I run 5Ks now which I was never able to do before in my 30s and 40s. JJ has been available to coach me with a individual plan while on vacation or at the office gym. He has also coached my son who had no fitness training prior and is very happy with his results. I can’t say enough great things about Coach JJ and his methods.
