What is CrossFit?

An excerpt from CrossFit.com:

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). 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 seminarsthroughout 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.

In 2003, we started a “new” blog that would spur a revolution in the fitness industry. The contents were simple: the date, a picture, the Workout of the Day (WOD), and usually some provocative nugget of information. Check out our first full month of posts back in May 2003.

Anyone with an Internet connection and the willingness, curiosity and bravery to try it, could. From this simple blog and a single gym in Santa Cruz, Calif., there sprung an immense community of fitness enthusiasts who have learned the movements, tested the theory and accumulated a huge amount of data supporting Glassman’s equation:

CVFM @ HI + Communal Environment = Health

A regimen of constantly varied (CV), functional movements (FM)performed at high intensity (@HI) in a communal environment leads to health and fitness.
