Move with purpose. Live with confidence.

The moment you step into the CrossFit Stealth Community you will be inspired to push a little harder, sweat a little longer, and believe in yourself a little more. With each day, you will move with purpose alongside a community that’s here to support you – no matter what.


What is CrossFit?​


CrossFit is a fitness program that builds general physical preparedness for all of life’s challenges. A blend of gymnastics, weightlifting, and mono-structural endurance, it does not specialize. It will never plateau. It is fun, creative, and, most importantly, it works. We teach you to do common things uncommonly well, while developing a base of strength and stamina on which you can build an active lifestyle. Our methodology thrives on the effort, commitment, and cooperation of a community that shares its successes; a community we want you to become a part of.
