I did a belly-dancing course last summer and LOVED it! I would have done the next course but I had my foot operated on at the same time so I couldn't do it. I'm going to be signing up again for the next one.
It's fun, it's great exercise and it gives you a really nice feeling about your body. you can do it at any size and that was totally apparent in my very diverse course that I took. I can highly recommend it
