Description

This exercise involves curling a dumbbell in one hand while in a prone position to target the biceps. It uses a hammer grip, which engages the forearms as well.

How to Do Dumbbell One Arm Prone Hammer Curl

  1. 1
    Setup

    Lie prone (face down) on an incline bench set at a 30-45 degree angle, allowing one arm to hang straight down towards the floor.

  2. 2
    Setup

    Hold a dumbbell in that hand with a neutral (hammer) grip, palm facing your body, ensuring your shoulder is stable and not shrugging.

  3. 3

    Keeping your upper arm stationary, exhale and slowly curl the dumbbell upwards towards your shoulder, contracting your biceps and forearms.

  4. 4

    Continue curling until the dumbbell is near your shoulder, ensuring your wrist remains straight and your elbow stays tucked close to your body.

  5. 5

    Inhale and slowly lower the dumbbell back to the starting position with control, fully extending your arm to feel a stretch in the biceps.

Tips

  • Focus on squeezing your biceps and forearms at the top of the movement to maximize muscle contraction, imagining you're trying to touch your shoulder with the dumbbell.
  • Maintain a stable torso throughout the exercise by engaging your core, preventing any rocking or swinging that could introduce momentum.
  • Keep your elbow fixed and pointing downwards, ensuring the movement comes solely from the elbow joint and isolates the target muscles effectively.
  • Control both the lifting and lowering phases of the curl; a slow, controlled eccentric (lowering) phase enhances muscle growth and reduces injury risk.

Common Mistakes

  • ×Swinging the dumbbell using momentum rather than muscle engagement; fix this by selecting a lighter weight and focusing on a strict, controlled movement.
  • ×Allowing the elbow to move forward or flare out during the curl; fix this by keeping your upper arm perpendicular to the floor and only bending at the elbow.
  • ×Not fully extending the arm at the bottom of the movement, which limits the range of motion; fix this by allowing the dumbbell to fully descend until your arm is straight before initiating the next repetition.
