Description

A variation of the traditional bicep curl, this exercise targets the biceps, forearms, and brachialis muscles by twisting the wrist during the curl motion.

How to Do Dumbbell One Arm Zottman Preacher Curl

  1. 1
    Setup

    Position yourself on a preacher curl bench, placing one upper arm flat on the pad with your arm fully extended and a dumbbell in hand, palm facing up.

  2. 2
    Setup

    Ensure your elbow is aligned with the top edge of the pad, keeping your shoulder relaxed and a slight bend in the elbow to protect the joint.

  3. 3

    Exhale as you curl the dumbbell upwards towards your shoulder, contracting your biceps and keeping your upper arm stationary against the pad.

  4. 4

    At the peak of the curl, rotate your wrist so your palm faces downwards (pronate), engaging your brachialis and brachioradialis.

  5. 5

    Inhale as you slowly lower the dumbbell back to the starting position with your palm still facing down, controlling the eccentric phase through a full range of motion.

  6. 6

    Once your arm is fully extended at the bottom, rotate your wrist back to the palm-up (supinated) position, ready for the next repetition.

Tips

  • Focus on the mind-muscle connection with your biceps during the concentric lift and your forearms during the eccentric lowering.
  • Execute the wrist rotation smoothly and deliberately at the top and bottom of each rep to fully engage the brachialis and brachioradialis.
  • Maintain constant tension on the muscle by not fully resting the weight at the bottom, stopping just short of full elbow extension.
  • Avoid shrugging your shoulder or lifting your elbow off the pad; this ensures that the bicep and forearm are the primary movers.

Common Mistakes

  • ×Swinging the weight: Do not use momentum or body English to lift the dumbbell; instead, keep the movement controlled and isolate the bicep.
  • ×Incomplete wrist rotation: Failing to fully pronate at the top and supinate at the bottom reduces the unique benefits of the Zottman curl for forearm development; ensure a complete and deliberate twist.
  • ×Lifting the elbow off the pad: Keep your upper arm and elbow firmly pressed against the preacher bench pad throughout the entire exercise to prevent shoulder involvement and maximize bicep isolation.
