Start by lying on your back with your arms by your sides and your palms facing down. Extend your legs fully with a slight bend in your knees. Lift your heels about 6 inches off the floor. Make small, rapid up and down scissor-like motions as you lift each leg to about 45 degrees into the air and lower your heel until it is about 2 - 3 inches off of the floor.
