Stand on tube with one foot, both handles in right hand.  Feet hip-width apart, knees soft, elbow firmly positioned next to hip.   Raise arm up toward shoulder, keeping body steady.  Take arm two inches shy of the shoulder, maintain resistance, and release until two inches from your leg, maintaining resistance the whole time.  You can reduce the intensity by gripping one tube in the working hand, and one tube in the resting hand.
