What is the 37 week pregnant belly dance? It is a belly dance done when the woman is 37 weeks pregnant. The significance of this is that the womans body is fully fleshed out in the curves of pregnancy and flush with the hormones from pregnancy. Yet she is still several weeks from her due date, and thus the 37 week pregnant belly dance does not pose a risk of causing labor as heavy exertion at a later point would. http://www.dvdfitness.net
