Working one arm at a time on the rope hammer preacher curl lets you square your shoulders to the pad and watch a single elbow do the job. The neutral rope grip still biases the brachialis, and the weaker arm sets the load, so both sides finish with identical work.
How to do the Rope Single Arm Cable Hammer Preacher Curl
- Attach a rope handle to a low pulley cable machine.
- Stand facing the machine with your feet shoulder-width apart.
- Grasp the rope handle with an underhand grip, palms facing up.
- Position your upper arm against the preacher bench pad, keeping your elbow slightly bent.
- Keep your back straight and your core engaged throughout the exercise.
- Slowly curl the rope handle towards your shoulder, keeping your upper arm stationary.
- Squeeze your biceps at the top of the movement, then slowly lower the rope handle back to the starting position.
- Repeat for the desired number of repetitions, then switch arms.
Tip: Lower for three seconds and stop just short of locking out the elbow to keep the muscle under tension.
Muscles worked
Common mistakes
- Elbows drifting forward — as the elbows come up the front delt starts to lift the weight; pin the elbows to your sides and let only the forearm move.
- Swinging from the hips — a small rock backward on each rep means the weight is too heavy; drop it and curl from a dead stop.
- Cutting the bottom short — stopping with the elbow bent shortens the range where the biceps are stretched; lower until the arm is nearly straight.
- Wrists curling at the top — flexing the wrist toward you brings the forearm flexors in; keep the wrist neutral or slightly extended.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Muscle growth | 3–4 × 10–15 per side | 60–90 s |
| Endurance / finisher | 2–3 × 15–20 per side | 45 s |
| Strength | Not ideal — pick a compound lift for the same muscle | — |
Curls go at the end of a pull session or arm day, after the rows and pulldowns that also load the biceps. Superset them with triceps pushdowns on the same cable stack or triceps extensions with the same dumbbells.

What can I do instead of the Rope Single Arm Cable Hammer Preacher Curl?
If you cannot do the Rope Single Arm Cable Hammer Preacher Curl, try the Leg Resisted Biceps Curl, the Side Lying Bodyweight Biceps Curl or the Single Arm Dumbbell Hammer Preacher Curl.

How many sets and reps should I do?
