About CrossFit

“CrossFit is the principal strength and conditioning program for many police academies and tactical operations teams, military special operations units, champion martial artists, and hundreds of other elite and professional athletes worldwide. And it is quickly becoming the strength and conditioning program for endurance athletes and everyday fitness enthusiasts.

CrossFit delivers a fitness that is, by design, broad, general, and inclusive. Our specialty is not specializing. Combat, survival, many sports, and life reward this kind of fitness and, on average, punish the specialist. The CrossFit program is designed for universal scalability making it the perfect application for any committed individual regardless of experience. We’ve used our same routines, scaling load and intensity, for elderly individuals with heart disease and elite athletes.”  – Courtesy of CrossFit Inc.
