How to do it

Sit at a preacher bench and rest the back of your upper arms on the pad, holding a dumbbell in each hand with a neutral grip. Curl the dumbbells up without rotating your wrists, squeezing at the top, then lower under control until your arms are nearly straight.

  1. 1Feel your biceps and forearms contract as you curl with palms facing each
  2. 2other
  3. 3Keep your upper arms pinned to the pad through the full range
  4. 4Lower slowly to feel the stretch at the bottom without losing tension

Common mistakes

  • Don't lift your elbows off the pad or swing to move the weight
  • Don't let your wrists bend or rotate
  • Don't cut the range short; extend almost fully at the bottom
