Description

An isolation exercise that targets the biceps brachii muscle, while also engaging the brachialis and brachioradialis for arm thickness.

How to Do Cable Rope One Arm Hammer Preacher Curl

  1. 1
    Setup

    Position a preacher curl bench in front of a low cable pulley and attach a single rope handle or a D-handle.

  2. 2
    Setup

    Sit on the preacher curl bench, placing the back of your upper arm firmly against the pad with your elbow aligned with the bottom edge.

  3. 3
    Setup

    Grab the rope handle with a neutral (hammer) grip, palm facing inward, ensuring your arm is fully extended and you feel a stretch in your bicep.

  4. 4

    Exhale as you curl the handle upwards towards your shoulder, contracting your bicep strongly at the top of the movement.

  5. 5

    Inhale as you slowly lower the handle back to the starting position, maintaining tension on the bicep throughout the full range of motion.

  6. 6

    Repeat for the desired number of repetitions, then switch arms and perform the exercise on the other side.

Tips

  • Maintain constant tension by not letting your arm fully relax at the bottom; keep a slight bend in the elbow to maximize time under tension.
  • Control the negative phase by slowly resisting the weight on the way down, taking 2-3 seconds to lower the handle, which enhances muscle growth.
  • Keep your elbow fixed and pressed against the preacher curl pad throughout the entire movement to effectively isolate the bicep and prevent cheating.
  • Focus on the hammer grip, as this neutral hand position specifically targets the brachialis and brachioradialis more effectively, contributing to overall arm thickness.

Common Mistakes

  • ×Lifting the elbow off the pad reduces bicep isolation; keep your elbow firmly pressed into the pad to maintain proper form and maximize bicep engagement.
  • ×Using momentum by swinging the weight takes tension off the bicep; ensure a controlled motion, focusing solely on bicep contraction to move the weight.
  • ×Not fully extending the arm at the bottom limits the range of motion; ensure a complete stretch in the bicep for optimal muscle engagement and development.
