Hi Shannon
I'm just finishing up my first ever Cathe's rotation (August, '07--got a late start and I take extra rest days--tee hee), but I'm loving it! It's really making a difference in my legs, butt and overall leanness (sp?). Next I'm going to try FitnessFreak's one body part per day rotation. I can't do high impact stuff either so I substitute walking or kickboxing. If you haven't checked out the rotations for Cathe and FitnessFreak, you might give those a try.

Chocolate IS the answer, regardless of the question.
