Awesome!!! Thanks for sharing. I, too am a yoga devotée. To compliment my weekly yoga class, I just started working through the courses in the "Light on Yoga" book.
I agree that it helps with flexibility, but I've also noticed that it's helping with strength too. I get through Warrior 1 and 2 with my own special mantra: IJS sit, IJS sit, IJS sit......Wish I could use the focus and concentration part to help deal with pre-preformance anxiety. Someday maybe I'll get there!
