I was doing cathe for a while before I ordered the P90x and I had almost her whole hardcore series. My favorite of the P90x is all of the upperbody workouts, I did legs for a while but backed off because they were getting a little too muscular with all my other workouts. I also love Yoga X...my whole body is sore for days after I do it and abripper is the best abs tape I have. Soooo definitely worth the price.
