Fitness, most broadly defined, is the ability to handle the demands of your life. Each of us has both different and unpredictable demands. A firefighter has no idea how big the fire will be on his next call, just as Grandma has no idea how heavy each grocery bag will be the next time she goes to the store. Very different concerns, for certain, but the ability to handle each requires the same basic abilities. As Coach Glassman has said for years, “The needs of our grandparents and soldiers differ in degree, not kind.” These needs are the functional competencies to move our own bodies and external objects through three-dimensional space.
The CrossFit exercises that we use are what we have found to be the most effective ways to build a broad, general and inclusive functional competence. Squatting, picking things up off the ground, putting things overhead, pulling ourselves up, running, jumping, throwing; these are the movements of life, and done with intensity, they prepare us for the demands of life.
