Start at the static push up position and have a partner lift up your feet using his hands. Your partner will walk in different directions and change directions and speed at will. You move using your body and arms and fists to remain relaxed and comfortable as possible. Remember to keep breathing and to find out how to keep your line of sight clear and free. Change roles and repeat a few times to learn to feel the changes in movement from the touch and to learn to navigate in different positions and limitations. Once you have done this repeat the drill facing up and if you cannot move using just your arms you will find a way to use shoulders and body and the rest of you to keep again as comfortable and free as possible.
