CrossFit begins with a belief in fitness. The aim of CrossFit is to forge a broad, general and inclusive fitness. We have sought to build a program that will best prepare trainees for any physical contingency — not only for the unknown, but for the unknowable. After looking at all sport and physical tasks collectively, we asked what physical skills and adaptations would most universally lend themselves to performance advantage. Capacity culled from the intersection of all sports demands would quite logically lend itself well to all sport. In sum, our specialty is not specializing.
CrossFit is many things. Primarily, it’s a fitness regimen developed by Coach Greg Glassman over several decades. He was the first person in history to define fitness in a meaningful, measurable way (increased work capacity across broad time and modal domains).
The CrossFit prescription is performing “functional movements that are constantly varied at high intensity.” CrossFit is a core strength and conditioning program. 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.
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:
Cardiovascular and Respiratory Endurance
The CrossFit method is to establish a hierarchy of effort and concern that builds as follows:
Diet: lays the molecular foundations for fitness and health.
Metabolic Conditioning: builds capacity in each of three metabolic pathways, beginning with aerobic, then lactic acid, and then phosphocreatine pathways.
Gymnastics: establishes functional capacity for body control and range of motion.
Weightlifting and Throwing: develop ability to control external objects and produce power.
Sport: applies fitness in competitive atmosphere with more randomized movements and skill mastery.
CrossFit itself is defined as that which optimizes fitness (constantly varied functional movements performed at relatively high intensity). CrossFit is also the community that spontaneously arises when people do these workouts together. In fact, the communal aspect of CrossFit is a key component of why it’s so effective.
Today, CrossFit, the company, provides accredited training seminars throughout the world. We publish several websites providing extensive free content, including workouts, training and support for becoming fit, as well as a growing Journal of extended instruction. We have a worldwide network of more than 5,500 affiliated gyms and more than 35,000 accredited CrossFit Level 1 trainers. And, we have created the Sport of Fitness, known as the CrossFit Games, where we crown the Fittest Man and Woman on Earth.
