Cable Preacher Curl

The Preacher Curl (Cable) is a supported biceps isolation exercise performed on a separate preacher bench facing a low pulley. The cable and attachment provide the resistance; unlike a preacher-curl machine, there is no integrated lever arm, and unlike an EZ-bar preacher curl, the load remains connected to the pulley.

Targets: Biceps
Equipment: Cable
Type: Isolation

Step by step

How to do the Cable Preacher Curl

Place a stable preacher bench in front of a low pulley and attach a straight or angled curl bar. Align the bench centrally so the cable clears its frame and runs toward your hands without rubbing the pad.
Choose a light starting load. With the stack resting, take the attachment securely, sit or stand at the bench as designed, and place the backs of your upper arms fully on the angled pad.
Set your chest close to the pad and keep your shoulders relaxed. Begin with the elbows extended only as far as you can control without hyperextending them or letting the cable pull your arms off the support.
Curl the attachment toward your shoulders by bending your elbows while keeping your upper arms heavy on the pad and your wrists in a comfortable, stable position.
Stop before the forearms lose useful cable tension or the shoulders roll forward, then lower slowly to the controlled start position.
After the set, keep hold of the attachment and guide it toward the pulley until the weight stack is fully down; do not release it while the cable is loaded.

Dropping quickly into full elbow extension under tension
Letting go of the attachment before the stack is resting

Safety: Secure the bench so it cannot slide toward the pulley and inspect the attachment connection before starting. Do not force the elbows past a comfortable straight position, and use a different handle or exercise if the setup causes wrist or elbow pain.
