The CrossFit prescription is “constantly varied, high-intensity, functional movement.” No aspect of functional movements is more important than their capacity to move large loads over long distances, and to do so quickly.
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.” The CrossFit methodology depends on full disclosure of methods, results and criticisms, and we’ve employed the Internet (and various intranets) 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.
In implementation, CrossFit is, quite simply, a sport—the “sport of fitness.” Harnessing the natural camraderie, competition, and fun of sport or game yields an intensity that cannot be matched by other means.
The modest start of publicly posting our daily workouts on the Internet beginning six years ago has evolved into a community where human performance is measured and publicly recorded against multiple, diverse, and fixed workloads.
