You Don’t Know Jack!

[youtube=http://www.youtube.com/watch?v=DqEi9OaH_Mo]”CrossFit is only for really fit people. I could never do that.” Really? Tell it to Jack. He’s 73 years young and he’s just as much a CrossFitter as 2012 CrossFit Games champ Rich Froning. We scale reps, weight/resistance, range of motion, intensity, etc to make CrossFit accessible to everyone. “The needs of Olympic athletes and our grandparents differ by degree not kind. One is looking for functional dominance; the other for functional competence. Competence and dominance manifest through identical physiological mechanisms.” -Greg Glassman; CrossFit Founder
