The cable bicep curl with a rope attachment effectively targets the biceps, providing constant tension throughout the movement. This exercise helps enhance bicep peak and overall arm strength, allowing for a greater range of motion and isolation.

1. Attach a rope to the low pulley of a cable machine.
2. Stand facing the machine, holding the rope with a neutral grip.
3. Keep your elbows close to your sides and curl the rope towards your shoulders.
4. Squeeze your biceps at the top of the movement.
5. Slowly lower the rope back to the starting position.
