The goal of CrossFit has been to forge a broad, general and inclusive fitness.


Aims of Crossfit

From the beginning, the aim of CrossFit has been to forge a broad, general, and inclusive fitness. We sought to build a program that would best prepare trainees for any physical contingency, to prepare them not only for the unknown but for the unknowable. 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.


Prescription

prescription

The CrossFit prescription is “constantly varied, high-intensity, functional movement.” Functional movements are universal motor recruitment patterns; they are performed in a wave of contraction from core to extremity; and they are compounded movements, i.e., they are multi-joint. They are natural, effective, and efficient locomotors of body and external objects. But no aspect of functional movements is more important then their capacity to move large loads over long distances, and to do so quickly. Collectively, these three attributes (load, distance, and speed) uniquely qualify functional movements for the production of high power. Intensity is defined exactly as power, and intensity is the independent variable most commonly associated with maximizing favorable adaptation to exercise. Recognizing that the breadth and depth of a program’s stimulus will determine the breadth and depth of the adaptation it elicits, our prescription for random physical challenges — i.e., unknown and unknowable events — is at odds with fixed, predictable, and routine regimens.

Methodology

methodology

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 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 spontaneous and collaborative online community. CrossFit is empirically driven, clinically tested and community developed.
