Merriam Webster’s Collegiate Dictionary defines “fitness” and being “fit” as the ability to transmit genes and being healthy. No help there. Searching the Internet for a workable, reasonable definition of fitness yields disappointingly little. Worse yet, the National Strength and Conditioning Association (NSCA), the most respected publisher in exercise physiology, in its highly authoritative "Essentials of Strength Training and Conditioning," does not even attempt a definition.
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 provide its own definition of fitness. That is what this episode is about: our “fitness.”
