What woman hasn’t dreamed of cloaking herself in exotic veils and gyrating her hips, sensually moving her belly, and gracefully reaching out her arms in a style that dates back to the 14th century BC? Now belly dancing classes are springing up everywhere to accommodate just that wish. “Belly dancing is an excellent way to get strong abdominal muscles,” notes Jiggins. “This is a form of dance that strongly emphasizes muscle groups in the abdomen, pelvis, trunk, spine, and neck by doing hip drops, circles, and rolls.” You can do this sexy exercise in a slow, undulating movement, which Jiggins estimates burns about 500 calories, or you can speed it up and do it to a samba beat, which burns about 700 calories. It's all a very popular twist on an ancient art, turning it into one of the best workouts for calorie burning.
