The cable superman curl is a biceps isolation exercise performed face down on the floor with the arms reaching overhead to a low pulley, curling the handle in while the trunk holds extension. Lying prone with the arms overhead puts the shoulder in flexion, which is where the long head of the biceps is at its longest, so the curl starts from a stretch no standing version reaches. The superman hold keeps the chest and arms off the floor, so the back and glutes work isometrically throughout. Lifters use it as a finisher for stretched-position biceps work.
What Muscles Does the Cable Superman Curl Work?
- Primary: Biceps brachii (long head), brachialis
- Secondary: Erector spinae, gluteus maximus, posterior deltoid
- Tertiary: Brachioradialis (upper forearm), rectus abdominis, wrist flexors
How Do You Set Up for the Cable Superman Curl?
Set a pulley at its lowest setting, clip on a straight bar or a rope, and lie face down on a mat with your head toward the stack, far enough back that the cable is tight with your arms straight. Take an underhand grip a little narrower than your shoulders. Squeeze your glutes, point your toes and lift your chest, arms and thighs off the floor so only your hips and ribs stay down.
How Do You Perform the Cable Superman Curl?
- Hold the superman position with the chest, arms and thighs off the floor and the arms straight overhead.
- Curl the handle toward your forehead by bending the elbows and keeping the upper arms where they are.
- Stop when the hands reach your hairline with the elbows still pointing forward and the chest still lifted.
- Squeeze for one count, keeping the pull of the cable against your palms.
- Straighten the arms slowly for a three count until the cable draws them back overhead.
- Reset the chest lift without letting the hands or thighs touch the floor between reps.
What Are the Key Form Cues?
- Keep the upper arms still: only the forearms move, so hold the elbows in the same patch of air from the first rep to the last.
- Chest up before the curl: set the superman lift first, then bend the elbows, so the back never trades height for range.
- Squeeze the glutes throughout so the lower back is not holding the position alone.
- Look at the floor a foot in front of your hands to keep the neck in line.
- Let the cable stretch the arms overhead at the bottom rather than pulling out of position.
What Are the Most Common Mistakes?
- Loading it like a standing curl: the cable drags you along the floor, so use a light stack and let the position dictate the weight.
- Cranking the neck and lower back to lift higher: the lumbar spine is extended under a pull from overhead, so lift only until the ribs clear the mat.
- Dropping the chest as the arms curl: the biceps get a shorter path and the back stops working, so hold the height through every rep.
- Letting the elbows drift down toward the floor: it turns into a pull rather than a curl, so keep them level with the shoulders.
- Lying too close to the pulley: the cable goes slack at the top and the squeeze is free, so shuffle back until it stays tight.
What Are the Best Cable Superman Curl Variations?
- Prone cable curl with the chest down: skip the superman hold to focus on the biceps alone.
- Single arm cable superman curl: one handle at a time, which shows up any twist through the trunk.
- Rope superman curl: a rope lets the wrists rotate out at the top for a harder squeeze.
- Incline bench cable curl: lying chest down on an incline bench raises the arms and removes the trunk hold.
- Overhead cable curl standing between two pulleys: the same stretched biceps angle without the floor position.
How Do You Progress the Cable Superman Curl?
- Add one plate on the stack only once the chest stays lifted for every rep.
- Build from 10 reps to 15 per set before any weight change.
- Add a third and fourth set as the lower back tolerates the hold.
- Hold the top squeeze for two seconds, then slow the return to a four count.
How Should You Program the Cable Superman Curl?
Place the cable superman curl at the end of an arm or pull session, after your rows and standing curls, once or twice a week. Work 3 to 4 sets of 10 to 15 reps with 45 to 60 seconds of rest, and stop the set when the chest starts dropping between reps. Pair it with a shorter-range curl such as a preacher curl so thebicepsget loaded at both ends.
