Cable Standing One Arm Hammer Curl With Rope Attachment
- Intermediate
- Isolation
- Rep-based
- Upper arms
This unilateral variation targets the brachialis and brachioradialis for improved arm thickness and forearm strength. Using a cable provides constant tension throughout the entire range of motion, maximizing muscle fiber recruitment compared to dumbbells.

Setup
- Set the cable pulley to the lowest position and attach a rope handle.
- Stand facing the machine and grasp one side of the rope with a neutral (palms facing in) grip.
- Step back slightly to create tension on the cable and adopt a staggered stance for better balance.
- Position your working elbow firmly against your side and engage your core to stabilize your torso.
How to do it
- Exhale and curl the rope toward your shoulder by flexing at the elbow while keeping your wrist in a fixed neutral position.
- Contract the bicep and forearm forcefully at the top of the movement for a one-second pause.
- Inhale and slowly lower the weight back to the starting position using a controlled 3-second eccentric tempo.
- Complete the full set on one arm before switching to the other side.
Form checklist
- Keep the elbow pinned to your ribs; do not let it swing forward or flare out.
- Maintain a neutral 'hammer' grip throughout the entire movement without rotating the wrist.
- Ensure the torso remains stationary; avoid leaning back or using momentum to move the weight.
- Fully extend the arm at the bottom of each rep to ensure a full range of motion.
Pro tips
- Slightly lean your torso toward the working arm to align the cable directly with the muscle fibers of the brachialis.
- Focus on 'crushing' the rope handle to increase neural drive and forearm activation through irradiation.
Make it harder
- Implement a 2-second pause at the peak of the contraction on every rep.
- Perform '1.5 reps' by curling to the top, lowering halfway, curling back to the top, and then lowering all the way down.
