If anybody is interested, I just came across an excellent 3-part video series on youtube called "Just My Size Yoga" with Megan Garcia. It is yoga for beginners and caters to overweight/obese yogis. These are very basic moves for people with little to no yoga experience. You can probably do all 3 parts in one session and helps to stretch and relax our bodies. This is a great workout for in between cardio/strength days.

I wanted to buy her dvd, but it looks to be sold out at most places.
