Is belly dancing a good workout?
Definately yes. I have been dancing for 10 years.
It's a lot of fun and I love getting dressed for class.
Another side effect is an improved self esteem. I take a local class through my community classes with a great teacher. Sohaila's basics to belly dancing [videorecording] Here is a tape by my teacher.
If you want to give it a try without spending money, go to your local library and see what tapes they have that you can borrow. This way you can test drive it.
