Power Yoga: Flexibility, with Rodney Yee. All in all, a nice sequence, but not really spectacular in any way. Generally I enjoy Yee's direction, and this was on par with my past experience, though at times (I suspect to fit into the compressed time frame) he moved a bit too quickly for my taste. I'm not sure exactly what makes this sequence more about flexibility than any other sequence, besides some variations in the downward-dog asanas in the Sun Salutations, but on the other side of things there was a bit of a nice workout in the small muscles of the shoulders.

Shape Challenge! - well, it made me smile (via Phil)
