About Us

What is CrossFit?

CrossFit begins with a belief in fitness. The aim of CrossFit is to forge a 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 sport and physical tasks collectively, we asked what physical skills and adaptations would most universally lend themselves to performance advantage. Capacity culled from the intersection of all sports demands would quite logically lend itself well to all sport. In sum, 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.

Why Us?

CrossFit is an evidence-based fitness program. 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, and repeatable facts, (i.e., data). The CrossFit methodology depends on full disclosure of methods, results and criticisms, and we’ve employed the Internet as our primary means to SUPPORT these values. Our charter is open source, making co-developers out of participating coaches, athletes and trainers through a spontaneous and collaborative online community. CrossFit is empirically driven, clinically tested and community developed.

We offer the world's most useful definition of fitness: increased work capacity across broad time and modal domains. Capacity is the ability to do real work, which is measurable using the basic terms of physics (force, distance and time). Life is unpredictable (much more so than sport) so real world fitness must be broad and not specialized, both in terms of duration and type of effort (time and modal domains).
