You're almost there! Tomorrow is Z!
As much as I love Leslie Sansone videos, she usually doesn't do enough stretching at the end. At the gym I used to go to, one of the trainers told us that we should stretch for at least ten minutes after aerobic exercise. I try to do that, but it gets pretty boring, just standing or sitting there, stretching and counting.
That's where yoga comes in. I have a DVD called "The Ten-Minute Solution: Yoga" (for beginners.) There are five different segments in it, so after a good aerobic walk, we just pop in a segment and stretch with Angie Stewart. Each one has a little different focus--energy, balance, etc., but each one is a pretty thorough whole-body stretch.
