I think STS Total Body (which I am overjoyed over) is heavy weights and High Reps is light weights similar to Power Hour. Different styles of weight training. HTH
That's correct Shoegoddess! Rose2boys, to help you watch the Power Hour film clip and notice how high the reps are. STS Total Body will not be like that at all. Plus it will include supersets and other high intensity training techniques that were used in STS.
