Lying Cable Curl
The lying cable curl has you lie on your back facing a low pulley, arms extended toward the machine, and curl a bar or handle up toward your shoulders. Lying down removes any chance of swinging your torso to help the lift, and the low pulley angle keeps tension on your biceps even at the bottom of the curl, where a dumbbell would normally go slack. It suits anyone who already curls comfortably and wants a stricter, more isolated version of the movement.
Why it works
A standing dumbbell curl loses most of its resistance at the very bottom, where your arm hangs straight down and gravity pulls straight along the bone rather than across it. Lying on the floor and pulling from a low pulley changes that angle entirely, so the cable keeps pulling your forearm away from your body throughout the full range, including the bottom, which means your biceps never really get to rest during the set. Being flat on the floor also takes your torso and legs out of the equation, so the only way to move the weight is by actually flexing your elbow.
Set up
- Attach a straight bar or handle to a low pulley and lie on your back a few feet away, feet toward the machine.
- Grab the attachment with both hands and extend your arms fully toward the pulley, palms facing up.
- Keep your upper arms resting lightly on the floor as your starting position.
How to do it
- Curl the bar up toward your shoulders by bending your elbows, keeping your upper arms still.
- Continue until your forearms are roughly vertical, feeling a strong contraction in your biceps.
- Pause briefly at the top of the curl.
- Lower the bar back down with control until your arms are fully extended again.
- Keep your shoulder blades and upper arms pinned to the floor for the entire rep.
Form cues
- Elbows stay glued to your sides.
- Only your forearms travel.
- Feel the stretch at the bottom, not just the squeeze at the top.
- Keep your lower back flat on the floor throughout.
Breathing: Exhale as you curl the bar up, inhale as you lower it back down.
Common mistakes
Letting the elbows drift up off the floor to help the bar travel higher.
Fix: Keep your upper arms resting on the floor throughout the set, so your biceps do the lifting instead of your shoulders.
Stopping the descent early instead of returning to a full arm extension.
Fix: Lower the bar all the way back down each rep so your biceps get the full stretch that this exercise is built to provide.
Rushing the tempo to grind out more reps with worse form.
Fix: Slow both the lift and the lowering down; the constant-tension benefit of this exercise depends on control, not speed.
How to program it
- Two or three sets of 10 to 15 reps works well, since this is a single-joint isolation move rather than a heavy strength lift.
- Place it toward the end of an arm or upper-body session, after any pulling exercises that already use your biceps as a secondary mover.
- Because the load stays light to moderate, twice a week is fine for most people without adding meaningful recovery demand.
Safety notes
- If you feel discomfort at the front of the elbow rather than muscle fatigue, lighten the weight and shorten the range slightly at the bottom.
- Keep your neck relaxed against the floor rather than straining it to watch your arms curl.

Frequently asked questions
How many sets and reps should I do for the lying cable curl?
Two or three sets of 10 to 15 reps is a solid range, since this move works best as a strict finisher for the biceps rather than a max-strength lift.
What can I do without a cable machine?
A standing dumbbell or barbell curl trains the same elbow flexion, though you'll need to focus extra hard on keeping your elbows still since there's no low-pulley angle helping you stay strict.
Lying cable curl vs standing cable curl, which is better?
Neither replaces the other; lying down removes any body swing and keeps tension on the biceps at the bottom of the curl, while standing is quicker to set up and still builds plenty of strength. Many lifters rotate between the two.
Why do I feel this more in my forearms than my biceps?
That usually means your grip is doing more work than it should, often because the load is heavier than your biceps alone can handle with strict form. Lighten the weight and focus on curling with your elbow rather than gripping harder.
