Yeah, the wife wants to do this in a few months. My buddy has it, but I think he stopped and is only doin a few of the DVD's. It is no joke from what he told me and he is pretty athletic. I could stand to lose a few (hundred) pounds....LOL! Not really, I only need to lose about 40lbs. and I would be fine. I know a lot of it has to do with nutrition. I use to eat right and I was sheding the pounds off when exercising.
