How to do it

Sit on a preacher curl bench and grab the EZ bar with an underhand grip. Rest your arms against the pad and curl the bar toward your shoulders. Pause at the top, then lower slowly until arms are extended.

  1. 1Keep your upper arms pinned to the pad and curl the bar so you feel your biceps doing all the work
  2. 2Lower under control until your arms are almost straight; you should feel a stretch at the bottom
  3. 3Squeeze hard at the top of each rep to feel a peak contraction in the belly of your biceps

Common mistakes

  • Don't let your elbows lift off the pad or swing the bar, this reduces biceps isolation
  • Avoid using your hips or shoulders to rock the weight up; keep your torso still
  • Don't let your wrists collapse backward; maintain a neutral wrist position throughout
