Feel Better and Live Longer.

Simply put, Rx Fitness Chantilly’s mission is to help you, “Change Your Life With Us.” After spending time in our facility and with our team we want our members to walk out of our doors after a workout and feel like they are better version of themselves. It isn’t the scientific sum of calories, workouts and weight that keeps our members returning. It is not the cutting edge equipment and technology. It is the people that count. Our team cares about guiding and encouraging each and every member to obtain the goals they seek for themselves. Our members’ goals are specific and if we can assist in that journey to realizing their aspirations then we have truly helped them change their life.
