Bellydance also has emotional benefits. Since movements are focussed on the centre of the body in the lower abdomen, it increases energy and an overall sense of well-being. It's the same kind of effect that people experience in yoga and martial arts.
It is also said that we hold our emotions in our abdomen. Don't we often say, 'I felt it in our gut.'? So, some say that all the exercise in that area helps us to release emotions we're holding onto. Whatever the other benefits may be, a toned abdomen is a very good thing to have!
