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 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. Our CrossFit program is designed for universal scalability, making it the perfect application for any committed individual, regardless of experience. We scale load and intensity; we don’t change programs.
