How to Do Dumbbell One Arm Hammer Preacher Curl

  1. 1
    Setup

    Position yourself on a preacher bench with one arm extended over the pad, holding a dumbbell with a neutral grip (palm facing in). Ensure your armpit is snug against the top edge of the pad and your triceps are fully supported.

  2. 2
    Setup

    Brace your core and keep your shoulder stable, allowing only your elbow joint to move throughout the exercise.

  3. 3

    Exhale as you slowly curl the dumbbell upwards towards your shoulder, contracting your biceps and forearms. Continue until your forearm is perpendicular to the floor or just before your bicep fully contracts.

  4. 4

    Inhale as you slowly lower the dumbbell back to the starting position, controlling the movement and fully extending your arm without locking the elbow. Repeat for the desired number of repetitions before switching arms.

Tips

  • Focus on the eccentric phase: Control the lowering portion of the curl for 2-3 seconds to maximize muscle fiber recruitment and growth.
  • Maintain a neutral grip: Keep your palm facing your body throughout the entire movement to effectively target the brachialis and brachioradialis.
  • Keep your elbow stable: Avoid lifting your elbow off the pad or allowing your shoulder to shrug, which can reduce tension on the target muscles and increase injury risk.
  • Full range of motion: Ensure a complete extension at the bottom and a strong contraction at the top, without resting at either extreme, to maximize muscle engagement.

Common Mistakes

  • ×Using momentum: Do not swing the dumbbell up; instead, use a controlled motion to ensure your biceps and forearms do the work.
  • ×Lifting the elbow off the pad: Keep your armpit firmly against the preacher bench pad to isolate the bicep and prevent shoulder involvement.
  • ×Incomplete range of motion: Fully extend your arm at the bottom and curl until your forearm is vertical to achieve maximum muscle activation.
