For about five minutes after a really good yoga class I feel amazing and wonderful and really thin and strong. Then I go into the locker room full of muscly somewhat emaciated people and all these feeling vanish. My great achievement of the day is doing a side plank modification which the teacher called "The Angry Rainbow." The Angry Rainbow looks sort of like this, only the top foot isn't on the ground and the hips are higher and my yoga pants aren't that crazy.
