CrossFit is constantly varied, functional movement, executed at a high-intensity.  CrossFit increases work capacity across broad time and modal domains.  In implementation, CrossFit is, quite simply, a sport—the “sport of fitness.” We’ve learned that harnessing the natural camaraderie, competition, and fun of sport or game yields an intensity that cannot be matched by other means.

The methodology that drives CrossFit is entirely empirical. We believe that meaningful statements about safety, efficacy, and efficiency, the three most important and interdependent facets of any fitness program, can be supported only by measurable, observable, repeatable facts; i.e., data. We call this approach “evidence-based fitness.”
