How to do it

  1. Set up the bar. Load it evenly, use collars, and take the grip on the angled part that suits your wrists.
  2. Elbows stay by the sides. No swinging the torso.
  3. Squeeze at the top, lower slowly to a straight arm.
  4. Keep the wrists neutral.
  5. Control every rep. Breathe out through the hardest part and stop the set when your form changes.

Common mistakes

  • Swinging the body. Use a weight you can lift with the trunk still.
  • Elbows travelling forward. Keep the elbows in place; the forearm moves, not the upper arm.
  • Skipping the bottom. Lower all the way to a straight arm before the next rep.
