What is CrossFit?

Constantly varied, functional movements performed at high intensity in a communal environment leads to health and fitness.

The aim of Pure Function 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 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.

The magic is in the movements.

All of CrossFit’s workouts are based on functional movements. These are the core movements of life, found everywhere, and built naturally into our DNA. They move the largest loads the longest distances so they are ideal for maximizing the amount of work done in the shortest time (intensity).

By employing a constantly-varied approach to training, these functional movements at maximum intensity (relative to the physical and psychological tolerances of the participant), lead to dramatic gains in fitness. Intensity is essential for results and is measurable as work/time. The more work you do in less time, the more intense the effort.

While it challenges the world’s fittest, the CrossFit program is designed for universal scalability, making it the perfect application for any committed individual, regardless of experience. We’ve used our same routines for elderly individuals with heart disease and cage fighters one month out from televised bouts. We scale load and intensity; we don’t change programs.
