HOW I TRAIN
I workout mostly at a CrossFit Affiliate
I workout mostly at home, work, or a traditional gym
I incorporate CrossFit.com workouts
I write my own programming
Stop looking as counter-example was found.
This athlete writes their own programming and incorporates crossfit.com workouts as an augmentation, not the base of their programming.
And since you picked Froning. It is very, very well known that he does whatever the hell he feels like everyday. He uses some crossfit.com WODs as the games approach to up his conditioning, but they are not the base of his programming and he has stated he doesn't use them year round.
