CrossFit begins with a belief in fitness. The aim of CrossFit is to forge broad, general, and inclusive fitness. We have sought to build a program that will best prepare trainees for any physical contingency — not only for the unknown, but for the unknowable. After looking at all sports and physical tasks collectively, we asked what physical skills and adaptations would most universally lend themselves to performance advantages. Capacity culled from the intersection of all sports demands would quite logically lend itself well to all sports. In summary, our specialty is not specializing.
CrossFit is many things. Primarily, it’s a fitness regimen developed by Coach Greg Glassman over several decades. He was the first person in history to define fitness in a meaningful, measurable way — increased work capacity across broad time and modal domains. CrossFit itself is defined as that which optimizes fitness: constantly varied functional movements performed at relatively high intensity. CrossFit is also the community that spontaneously arises when people do these workouts together. In fact, the communal aspect of CrossFit is a key component of why it’s so effective.
