CrossFit is a strength and conditioning program based on constantly varied, high intensity, functional movements.
Constantly varied movements are movements that keep the body from adapting to the same neurological responses over and over again. Variation keeps the body guessing and is responsible for great muscular results. High intensity is a form of anaerobic exercise of short intense exercise with less intense recovery periods. These short, intense workouts provide for improved fitness and conditioning, better internal glucose metabolism, and efficient fat burning capabilities. Functional movements are movements humans were built for. Movements that are natural and safe and used in everyday life, squatting, picking things up, putting things down are all essential to allow you to function in everyday life and lead to better health and fitness.
