How to do it

Starting position

  1. Anchor the band at navel height and stand sideways.
  2. Grip the band with the hand farther from the anchor point.
  3. Bend your elbow to 90 degrees and keep it against your side.
  4. Tucking a towel into your armpit keeps your elbow from drifting away.

Movement

  1. Keep your elbow against your side and rotate the back of your hand outward.
  2. Brace your core and resist so your torso does not rotate.
  3. Pause briefly at the point where you cannot rotate any further.
  4. Slowly return toward your belly button while resisting the pull of the band.

Breathing

Exhale as you rotate outward, inhale as you return.

Cautions

  • If you use a heavy band, you will twist your torso and cheat. Choose a lighter one.
  • If your elbow moves away from your side, your front delt takes over.
  • If you feel a sharp pain inside your shoulder, stop and reduce your range of motion.
