How to do it

Starting position

  1. Anchor the band to a bench leg or a low point near your head.
  2. Lie down, grip the ends with both hands, and extend your arms straight above your chest.
  3. Keep your elbows shoulder-width apart and keep them pinned.

Movement

  1. Keep your elbows fixed in place and bend your arms to bring your hands toward your forehead.
  2. Pause briefly above your forehead.
  3. Extend your arms straight again using your triceps.

Breathing

Inhale as you bend, exhale as you extend.

Cautions

  • If your elbows flare out, your chest works instead.
  • If your arms shift toward your head, it becomes a pullover. Keep your elbows pinned.
