How to Do Hammer Curls: Proper Form and Technique

Master the hammer curl to build thicker arms and stronger forearms. Follow our guide for proper dumbbell technique and common mistakes to avoid.

How to Perform

  1. Stand upright with your feet shoulder-width apart and hold a dumbbell in each hand with your palms facing your torso.
  2. Keep your elbows tucked close to your sides and maintain a neutral grip throughout the entire movement.
  3. Exhale and curl the weights upward by contracting your biceps until the dumbbells reach shoulder level.
  4. Pause for a moment at the peak of the contraction to maximize muscle tension.
  5. Inhale and slowly lower the dumbbells back to the starting position in a controlled manner.
  6. Ensure your torso remains stationary and avoid using momentum to lift the weights.

Common Mistakes

  • Using shoulder momentum or swinging the torso to assist the lift.
  • Allowing the elbows to drift forward or away from the ribs.
  • Rotating the wrists into a palms-up position rather than keeping them neutral.
  • Failing to fully extend the arms at the bottom of the repetition.
