Well, tennis and racquetball destroyed my knees and I needed to try something before I became a couch potato. I have started out in the Level 1 classes three times a week. So far so good: I work up a sweat while I stretch and push my muscles. I was surprised at the effort needed to go through the positions slowly. I still feel like a clumsy hippo, I fall over a lot, but I feel better and hope to get rid of my potbelly.
