Cable Rope Hammer Preacher Curl
- Intermediate
- Isolation
- Rep-based
- Upper arms
This isolation exercise targets the brachialis and brachioradialis by using a neutral grip, while the preacher bench eliminates momentum for maximum tension. It is highly effective for building thickness in the arms and improving forearm strength.

Setup
- Position a preacher bench in front of a low cable pulley with a rope attachment.
- Sit or stand at the bench and grab the rope with a neutral grip (palms facing each other).
- Rest your upper arms firmly against the pad, ensuring your armpits are snug against the top edge.
- Extend your arms fully toward the pulley to establish the starting position.
How to do it
- Exhale as you curl the rope toward your shoulders, keeping your wrists neutral and your upper arms glued to the pad.
- At the top of the movement, squeeze your biceps and forearms hard for one second.
- Inhale as you slowly lower the weight back to the starting position using a controlled 3-second eccentric phase.
- Stop just short of full elbow lockout to maintain constant tension on the muscles.
Form checklist
- Keep your wrists straight and rigid; do not let them collapse under the weight.
- Ensure your shoulders remain down and back, avoiding the urge to hunch forward.
- Keep your elbows tucked and stationary on the pad throughout the entire range of motion.
- Maintain a stable torso and avoid leaning back to 'swing' the weight up.
Pro tips
- Pull the ends of the rope slightly apart at the top of the curl to intensify the contraction in the brachialis.
- Focus on the 'mind-muscle connection' by imagining you are pulling the weight with your forearms rather than just your hands.
Make it harder
- Incorporate a 2-second pause at the mid-point (90-degree angle) of each repetition to increase time under tension.
- Perform a 'drop set' by immediately reducing the weight by 20-30% after reaching failure to further exhaust the muscle fibers.
