What is Fitness

The article defines CrossFit's three standards of fitness: 1) competency across 10 general physical skills, 2) ability to perform a variety of physical tasks, and 3) competency across the 3 metabolic pathways (phosphagen, glycolytic, oxidative). It then discusses how CrossFit implements training to develop fitness per these standards, focusing on metabolic conditioning/cardio via interval training to balance anaerobic and aerobic work, as well as strength training and gymnastics. The goal is to produce athletes equally skilled in weightlifting, gymnastics, and sprinting for the broadest, most general fitness.
