How to do it

Starting position

  1. Sit on a chair or the floor and loop a towel under your feet.
  2. Grip both ends of the towel with a neutral grip, palms facing each other.
  3. Keep your elbows pinned to your sides.
  4. Keep your back straight and brace your abs.

Movement

  1. Press down on the towel with your legs to create resistance.
  2. Curl both hands toward your shoulders at the same time against that resistance.
  3. Pause briefly at the top, squeezing your biceps.
  4. On the way down, keep pressing with your legs to resist as you slowly straighten your arms.

Breathing

Exhale as you raise, and inhale as you lower.

Cautions

  • Since the weight is not displayed, increase the reps or press down harder to raise the intensity.
  • If you press harder and resist on the way down rather than on the way up, the tension will be much greater.
  • If you lean your torso back to use momentum, your lower back works instead of your biceps.
  • Keep your wrists neutral so they do not bend inward or outward.
