Lie on the floor, with your arm extended above you and the foot of the same side planted close to your butt. Your other arm should be extended across the floor at about 45 degrees. Drive the foot into the ground to roll the hip over, and allow you to roll up onto the elbow of the extended arm, keep the raised hand directly above you. Continue to rise up onto the hand. To descend, lower down onto the elbow, then roll down onto the shoulder and back.
