Yoga X

I'm now into my 4th week of P90X. When I first attempted the Yoga X session, I didn't think I would like it after the 1st day. Well I've done Yoga X 4 times so far and I must say that I do enjoy it very much. It is long, however, since the movements are slow and drawn out, the time does go by.  I will add that I enjoy the first 45 minutes (roughly the halfway point) because I know I'm getting a great workout. I sweat so much during the 1st half. Thinking about the 2nd half, it is very difficult for me. I found myself sitting and watching Tony and the crew do the most difficult things that I simply could not do. I do try, yet I just find that my body just cannot get into some of those positions. I noticed that because I couldn't do the same amount of workout during the 2nd half, I didn't sweat as much. If I were to revise Yoga X, I would change the 2nd half so that it can accommodate those who just can't do those difficult positions
