Have you all heard about these online workouts? They seem to have great success. I did the first work out of the 30 challenge last night and holy cow my legs and rear are killing me today!!! I took a look at the next day's work out and oy vey it looks even worse! I am going to try to do it... tomorrow... today it just hurts to much lol. Has anyone else ever tried these at-home online workouts at www.bodyrock.tv??
