I"m not familiar with either of these programs, but I seem to remember one of our members has ordered the P90X, I think. I'm very sorry, but right off hand, I can't remember which one it was. Hopefully, she will see your post and answer or I will remember who it was and contact her for you.......
Personally, I like yoga for toning and all around exercise. It works the entire body AND helps you relax. My favorite dvd is "Biggest Loser, Yoga for Weight Loss".
