Cable Curl

Body Part: Arms

Muscle: Biceps

Equipment: Cable Machine

The Cable Curl is a biceps exercise performed from a low cable pulley with a handle, straight bar, or curl attachment. The cable keeps steady tension on the biceps through the lift and lower, while the brachialis, brachioradialis, wrist flexors, and forearms assist.

Unlike dumbbells, the cable keeps pulling throughout the entire range, so the bottom and top both need control. The elbows should stay near the sides, the wrists should remain neutral, and the torso should stay upright instead of leaning back to move the weight.

Set a low pulley, attach a comfortable handle or bar, and stand tall holding it with an underhand grip. Curl by bending the elbows, squeeze the biceps near the top, then lower slowly until the arms are extended. Keep the cable line smooth and avoid letting the stack slam down.

Use Cable Curls as a main biceps accessory or as a higher-rep finisher when you want constant tension. Attachment choice can change comfort and emphasis, but strict elbow flexion remains the priority. Reduce the load if the shoulders or torso start helping.

Instructions

• Set the cable pulley low and attach a straight bar, curl bar, rope, or single handle.
• Stand facing the cable machine and hold the attachment with an underhand grip when using a bar.
• Step back just enough to create cable tension at the bottom.
• Brace your core and keep your elbows near your sides.
• Curl the attachment upward by bending your elbows.
• Squeeze the biceps near the top without letting the elbows drift far forward.
• Lower the attachment slowly until the arms extend again.
• Repeat while keeping the torso still and cable movement smooth.

Tips & Tricks

• Choose an attachment that keeps your wrists comfortable.
• Keep the elbows close to your ribs so the shoulders do not take over.
• Do not lean back or hip thrust to start the curl.
• Control the return so the weight stack does not slam.
• Keep the wrists neutral instead of curling them toward your forearms.
• Use a full lower until the biceps stretch without losing posture.
• Pause briefly at the top if you can keep the elbows steady.
• Stand far enough from the pulley that the cable stays lightly loaded at the bottom.

Frequently Asked Questions

What muscles does the Cable Curl work?

It mainly works the biceps, with help from the brachialis and forearms.

Why use cables for curls?

Cables provide consistent tension and can feel smoother than free weights.

Should my elbows move?

Keep them mostly still so the biceps do the work.

Which attachment should I use?

Use the attachment that feels best on your wrists, such as a straight bar, EZ-style curl bar, rope, or handle.

Where should the pulley be?

Set it low so the cable pulls from near the floor throughout the curl.

Can I go heavy on Cable Curls?

Use a challenging load only if you can keep the torso still and elbows controlled.

Why does the cable curl feel different from dumbbells?

The cable provides constant tension, especially at points where dumbbells may feel easier.

What is the biggest mistake?

Leaning back and letting the shoulders pull the attachment instead of curling with the biceps.
