Sidewinder
This is like moon walk on your side, really cool and easy move to learn.
Lay down on the ground on your left side. Bend your elbows to a 90º angle and move in a circular motion. Your knees are bend and move as you would normally walk. Use your left arm to push your upper body back while your doing the circular motion, and push your lower body back with your left leg. This move is not hard at all, just keep practice until you have a smooth motion.
