Description

A variation of the classic preacher curl that targets the biceps and forearms.

How to Do Dumbbell Alternate Hammer Preacher Curl

  1. 1
    Setup

    Sit on a preacher curl bench with your chest against the pad and the top of the pad under your armpits.

  2. 2
    Setup

    Hold a dumbbell in each hand with a neutral grip (palms facing each other) and extend your arms fully over the pad, ensuring your triceps rest firmly.

  3. 3

    Keeping your upper arm stationary and pressed against the pad, exhale and curl one dumbbell upward by contracting your bicep until your forearm is vertical.

  4. 4

    Squeeze the contraction at the top, then slowly inhale as you lower the dumbbell back to the starting position with controlled movement, fully extending your arm.

  5. 5

    Alternate arms, repeating the curl with the other dumbbell, maintaining constant tension and form throughout the set.

Tips

  • Focus on the negative: Control the eccentric (lowering) phase for 2-3 seconds to maximize muscle fiber recruitment and growth.
  • Keep your elbows locked: Ensure your upper arms remain completely still on the pad to isolate the biceps and prevent shoulder involvement.
  • Maintain neutral grip: Keep your palms facing each other throughout the entire movement to emphasize the brachialis and brachioradialis effectively.
  • Full range of motion: Fully extend your arm at the bottom to get a complete stretch in the biceps and allow for a stronger contraction.

Common Mistakes

  • ×Swinging the weight: Avoid using momentum from your torso or shoulders; instead, reduce the weight to perform the curl with strict bicep contraction.
  • ×Lifting elbows off the pad: Do not let your elbows lift from the preacher pad during the curl; keep them firmly pressed to maintain isolation and prevent injury.
  • ×Incomplete range of motion: Failing to fully extend the arm at the bottom or fully curl at the top limits muscle activation; ensure a complete, controlled movement for optimal results.
