Key Grip with Towel (Lateral Prehension Grip)

Key Grip with Towel (Lateral Prehension Grip)

Make a "thumbs up" sign with your hand (fingers curled into a fist with thumb pointed toward the ceiling). Place a folded hand towel between your thumb and the top side of your first finger (the same way you would pinch a key). Squeeze the towel between your thumb and side of your first finger, hold as directed, then relax and repeat.
