Description

A dumbbell reverse preacher curl is an exercise that targets the brachialis muscle, which lies underneath the biceps brachii. This exercise is performed on a preacher bench using one dumbbell.

How to Do Dumbbell One Arm Reverse Preacher Curl

  1. 1
    Setup

    Position yourself on a preacher bench, resting the back of your upper arm firmly against the pad.

  2. 2
    Setup

    Grasp a dumbbell with an overhand grip (palms facing down), ensuring your arm is fully extended and your wrist is straight.

  3. 3

    Exhale and slowly curl the dumbbell upwards towards your shoulder, focusing on contracting your brachioradialis.

  4. 4

    Continue curling until your forearm is perpendicular to the floor, or just before your wrist starts to lose tension.

  5. 5

    Inhale and slowly lower the dumbbell back to the starting position with controlled movement, resisting the weight throughout the entire descent.

Tips

  • Maintain a neutral wrist throughout the movement; avoid any wrist flexion or extension to keep tension on the target muscle.
  • Focus on initiating the curl with your forearm muscles rather than swinging with your biceps or shoulder.
  • Control the eccentric (lowering) phase for 2-3 seconds to maximize muscle fiber recruitment and growth.
  • Keep your elbow fixed against the preacher pad to isolate the forearm and brachioradialis effectively.

Common Mistakes

  • ×Using wrist flexion to lift the weight instead of forearm strength strains the wrist; keep your wrist straight and rigid throughout the movement.
  • ×Relying on momentum to swing the dumbbell up reduces muscle engagement; perform the movement slowly and deliberately, focusing on muscle contraction.
  • ×Failing to fully extend the arm at the bottom limits the range of motion; ensure a complete stretch at the bottom of each repetition.
