I finally did Great Glutes yesterday, without the discs premix but with the bonus chair. WOW!!!!! My bum feels so firm this morning, I cannot believe it. Cathe should have called this Firm Glutes. I love the hamstring work as well. The only reason I didn't do the disc portion is because I had just done Slide N Glide before and didn't need anymore disc work. The only exercise I had problems with is the low lunges when you put your knee on the floor, then slightly lift it off the floor. My knees didn't like too many of those, so I only did 4 on each side. I'll have to try to work on those for the future. But the bun blaster is definately the floor work at the end. OMG!!!!!! Great work Cathe and thanks for the Great glutes and Lean legs.
