CrossFit is exercise-in the broadest most comprehensive sense of the word. It's designed to make you better, in every way. A faster runner, a stronger lifter, more flexible, more agile, more powerful, more athletic, more tough. CrossFit makes you a better human being. If you need to lose bodyfat, gain some muscle, become more coordinated, or be mentally stronger, following the program will do it. No matter where you start.
In CrossFit you're never alone. Your coach always explains your workouts, teaches technique, and listens to your feedback. Your classmates train by your side, offer motivation, and rely on you.
CrossFit isn't for everyone, but it is for ANYONE.
