Seriously, I was worried I'd be walking crooked after all that. I can feel it in my upper arms and a little bit in my stomach muscles, which is good. Yoga for me is a nice combination of cardio with a spiritual twist. I like to do it prior to evening prayer or compline. (I didn't do either last night, probably should have considering I was a raging wildabeast of mean yesterday.) The whole combination opens me up spiritually and makes me feel better over all. Plus, I'm pretty sure this also counts as strength training, since I spent a lot of time in that thing they call 'plank position' and stuck one leg in the air a lot.
Yeah... I don't know if I could ever do this stuff with other people.
