This was a power yoga class - lots of stretching, holding poses, and some difficult moves. The room is 105 degrees F. It was difficult for me - I didn't know the positions and I couldn't do a lot of them very well. I was happy I didn't fall over. But I am happy I went. I have been wanting to do this for a long time and I kept procrastinating and cancelling after signing up. Finally I ran out of excuses. I have signed up and paid for 8 classes a month for the next two months. Paying for something makes me feel obligated to do it. But anyway, I feel great. It was hard for me, but the instructor was supportive, and hopefully next class will be just a little bit easier.
