WHAT IS CROSSFIT?
CrossFit is primarily a fitness regimen of constantly varied functional movements performed at relatively high intensity in a communal environment. It is meant to increase work capacity across broad time and modal domains throughout the lifespan. This translates to the ability to perform many different tasks (e.g. squat, run, lift) under different loads (e.g. body weight, barbell, medicine balls) over varying time frames (e.g. 30 seconds, 20 minutes). It is about developing the ability to do real work and real tasks in a safe, efficient, and effective way. This regimen prepares you for the predictable, the unknown, and the unknowable.
