The official definition of CrossFit is: constantly varied, functional movements executed at high intensity. It is a training philosophy that coaches people of all shapes and sizes to improve their physical well-being and cardiovascular fitness.
What this means is that CrossFit workouts (WODs) utilize a wide range of movements that have practical equivalents in everyday life. The “sport of fitness” specializes in not specializing; it focuses on getting a person as fit as he/she can be across all major physical skills including strength, endurance, flexibility, stamina, and coordination.
Because of this, CrossFit can benefit you no matter what your goals, background, or athletic ability. In other words: you can do CrossFit, and CrossFit can help you change your life for the better.
