What is CrossFit?

CrossFit is a fitness regimen developed by Greg Glassman over several decades. Glassman, CrossFit’s Founder and CEO, was the first person in history to define fitness in a meaningful, measurable way: increased work capacity across broad time and modal domains. He then created a program specifically designed to improve fitness and health.

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 more. These are the core movements of life. They move the largest loads the longest distances, so they are ideal for maximizing the amount of work done in the shortest time. 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 dramatic gains in fitness.

CrossFit Community

The community that spontaneously arises when people do these workouts together is a key component of why CrossFit is so effective, and it gave birth to a global network of CrossFit affiliates that number over 13,000. Harnessing the natural camaraderie, competition and fun of sport or game yields an intensity that cannot be matched by other means.

The CrossFit program is driven by data. Using whiteboards as scoreboards, keeping accurate scores and records, running a clock, and precisely defining the rules and standards for performance, we not only motivate unprecedented output but derive both relative and absolute metrics at every workout. This data has important value well beyond motivation.

Overall, the aim of CrossFit is to forge a broad, general and inclusive fitness supported by measurable, observable and repeatable results. The program prepares trainees for any physical contingency—not only for the unknown but for the unknowable, too. Our specialty is not specializing.

While CrossFit challenges the world’s fittest, the program is designed for universal scalability, making it the perfect application for any committed individual, regardless of experience. We scale load and intensity; we don’t change the program. The needs of Olympic athletes and our grandparents differ by degree, not kind.

The Ten General Physical Skills

The CrossFit program is designed to elicit as broad an adaptational response as possible. CrossFit is not a specialized fitness program but a deliberate attempt to optimize physical competence in each of ten recognized fitness domains. They are as follows:

Speed – The ability to minimize the time cycle of a repeated movement.
Coordination – The ability to combine several distinct movement patterns into a singular distinct movement.
Agility – The ability to minimize transition time from one movement pattern to another.
Balance – The ability to control the placement of the bodies center of gravity in relation to its support base.
Accuracy – The ability to control movement in a given direction or at a given intensity.
Cardiovascular/respiratory endurance – The ability of body systems to gather, process, and deliver oxygen.
Stamina – The ability of body systems to process, deliver, store, and utilize energy.
Strength – The ability of a muscular, or combination of muscular units, to apply force.
Flexibility – the ability to maximize the range of motion at a given joint.
Power – The ability of a muscular unit, or combination of muscular units, to apply maximum force in minimum time.
