Shimmy belly dancing is one of the tactics that a belly dancer must be familiar with. Like many of the other movements, it relies on an isolation of certain muscle groups, which in this case are the knees and hips. To perform shimmy belly dancing, the performer should stand in the right posture, get the motion down, start off slowly and then speed it up. Once you get the technique down, you can pick up the pace. It should be almost seamless in movement, and your knees will pump as quickly as they can go. http://www.dvdfitness.net
