CrossFit is group fitness training that is composed of “constantly varied, high-intensity, functional movement” (from the CrossFit Journal Articles, 2007). It includes aerobic exercise, bodyweight strengthening, calisthenics and gymnastics, and weightlifting principles. CrossFit’s aim is to improve the following tenets of physical fitness: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy (from The CrossFit Guide for Beginners (Must Know Before You Start), 2019).
