What is Crossfit?

Understanding CrossFit

We sought to build a program that would best prepare trainees for any physical contingency – prepare them not only for the unknown but for the unknowable as well.

What is fitness?

For CrossFit the specter of championing a fitness program without clearly defining what it is that the program delivers combines elements of fraud and farce. The vacuum of guiding authority has therefore necessitated that CrossFit’s directors provide their own definition of fitness. That’s what this issue of CrossFit Journal is about, our ‘fitness.’

CrossFit is a core strength and conditioning program. We have designed our program 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 Cardiovascular and Respiratory endurance, Stamina, Strength, Flexibility, Power, Speed, Coordination, Agility, Balance, and Accuracy.
