The Method

The CrossFit method is to establish a hierarchy of effort and concern that builds as follows:

Diet:  Lays the molecular foundations for fitness and health

Metabolic Conditioning:  Builds capacity in each of three metabolic pathways, beginning with aerobic, then lactic acid, and then phosphocreatine pathways

Gymnastics:  Establishes functional capacity for body control and range of motion.

Weightlifting and throwing:  Develop ability to control external objects and produce power.

Sport:  Applies fitness in competitive atmosphere with more randomized movements and skill mastery.
