Exercise Advice: Sit on an exercise ball while holding the handles of an elastic exercise band in each hand. The band must be anchored by being placed beneath the exercise ball that you are sitting on. Next, simply perform a regular one arm bicep curl by slowly curling the handle in your left hand trying to touch it to your left shoulder. While you are performing the movement, turn (i.e., supinate) your palm outward and squeeze your bicep for a one-count at the top of the movement. Slowly lower the handle to the start position and repeat with your right arm.
