There's a guy at my gym who does it. He's a big fan, always advertising. I have to admit he's pretty buff too, 6'1" 235ish about 10%BF, not bad for brief, simple workouts. Plus, he indicates that it ties diet and training together in the program. He looks a little goofy with the Flav-o-Flav stopwatch around his neck to time the intervals, or whatever you BFL people do?!? But he is making good progress, and, in general, structured programs are good to not waste time. I personally prefer stints of Westside and HST for now, but most individuals I know who do Body for Life look good, do well, and serve as good ambassadors for the system. It has me curious. I say give it a try and let us all know!
