Zumba
It has become one of the fastest-growing, dance-based fitness crazes in the country. People of all ages can enjoy the easy-to-follow dance moves, while getting their body in shape at the same time.

Hula hooping
Hooping classes can burn up to 100 calories in 10 minutes of twisting. That's the same rate as running at a moderate pace.

Along with healthy heart benefits, hula hooping offers a great workout for your abdominal core. Stomach muscles are used in most everyday activities, so this is important to help cut the risk of back pain and injury.

Belly dancing
It works several muscle groups, and is a graceful, fun and exciting new form of now-mainstream exercise. Different movements target different areas of the body. For example, shoulder shimmies are great for the arms and back. Hip drops give the midsection and legs a workout.
