I have read various posts regarding the Power 90x workouts, and most have said that in doing the program, they have subbed Cathe leg workouts for the Power 90x legs routine. I was curious if anyone has had any success with just following the Power 90x program to the letter, as far as the legs and booty go. I love the workouts, but just wanted to know if I doing the legs workout is a waste of time. Thanks, Alicia
