Take XerTube in left hand, grabbing handle with palm facing up.  Take free handle in right hand and reduce the length of the tube to increase resistance.  Pull your right arm securely in next to chest, where it remains without movement.  Position left hand above head, with forearm parallel to the ground.  Extend this arm up toward the ceiling, offering resistance from the XerTube on the way up, as well as on the way down.
