What Is CrossFit?
CrossFit is constantly varied functional movements performed at high intensity. All CrossFit workouts are based on functional movements, and these movements reflect the best aspects of gymnastics, weightlifting, running, rowing and other exercises. These are the core movements of life. They are ideal for maximizing the amount of work done in the shortest time because they move the biggest loads the greatest distances.
Intensity is essential for results and is measurable as work divided by time—or power. The more work you do in less time, or the higher the power output, the more intense the effort. By employing a constantly varied approach to training, functional movements and intensity lead to huge gains in fitness.
