I also watched the "Rock Bodies" show and it was pretty much a waste. As a personal trainer myself, I was shocked at some of the high risk exercises that some of the trainer's use on their clients. As for Britney's 150 crunches--what's the big deal about that. I routinely put my clients through at least that number of varying crunches and ab moves. I bet if you counted the number of crunches that Cathe puts you through at the end of Pure Strength Legs and Abs it would be much more than 150 (that is the only Cathe video I have so far so that is the only one I can refer to but I am sure the others have just as rigorous ab sections). As for colonics, what a bunch of poo-poo--pun very much intended! If someone is eating an adequate amount of fiber and their digestive system is functioning properly, there is no need to flush the system. I am sorry, but things are only supposed to come OUT of that area of my body, there is no way I am going to pay someone to put something in there! I second the previous poster's comment on Kelly Price and how she is being sensible about her weight loss methods and is not trying to become like the stick thin icons of today.
