Barbell Curls Lying Against An Incline
This curl has you lying face down against a steep incline bench, arms hanging straight down holding a barbell, curling it up toward your chin. Lying prone pins your shoulders against the pad so there's no way to swing your torso or lean back to help the bar up, which makes it one of the stricter ways to isolate the biceps. It's a good fit for anyone whose standing curls turn into a hip-swinging exercise by the last couple reps.
Why it works
A standing barbell curl lets you lean back slightly or drive your hips forward to help the bar past the sticking point, especially as fatigue sets in. Lying chest-down against an incline removes that option entirely, since your torso is pressed flat against the pad and can't move independently of your arms. That leaves the biceps as the only muscle group that can actually move the weight, which is why this variation is used when the goal is pure biceps isolation rather than moving the heaviest weight possible.
Set up
- Set an incline bench to roughly 45 to 60 degrees and lie face down against it, chest and stomach pressed into the pad.
- Let a barbell hang straight down at arm's length, gripping it shoulder-width apart with palms facing away from you.
- Rest your forehead lightly on the top of the pad or hold your head up neutrally, whichever keeps your neck comfortable.
- Let your shoulders relax down and back before the first rep, rather than shrugging up toward your ears.
How to do it
- Curl the barbell up by bending your elbows, keeping your upper arms pinned against the sides of the bench.
- Continue until your forearms are close to vertical or your biceps are fully contracted, without shrugging your shoulders to finish the rep.
- Pause briefly at the top and squeeze the biceps.
- Lower the bar slowly under control back to a full arm hang before starting the next rep.
- Keep your torso pressed flat against the incline the entire time, resisting any urge to push away from the pad.
Form cues
- Chest stays pinned to the pad the whole rep.
- Elbows stay still, only the forearm moves.
- No shrugging at the top of the curl.
- Lower slowly, don't just drop the bar.
Breathing: Exhale as you curl the bar up toward your chin, inhale as you lower it back to a full arm hang.
Common mistakes
Letting the elbows drift forward away from the bench as the bar gets heavy.
Fix: Reduce the weight until you can keep your upper arms pinned against the pad for every rep in the set.
Shrugging the shoulders up to help finish the curl near the top.
Fix: Stop the rep a few degrees short of full contraction if that's where the shrug starts, and build range gradually as biceps strength improves.
Dropping the bar quickly on the way down instead of controlling the lowering phase.
Fix: Count two to three seconds on the way down; that eccentric phase is where a lot of the growth stimulus from this exercise comes from.
How to program it
- This is a single-joint biceps isolation move, so 3 sets of 8 to 12 reps at a controlled tempo works well.
- Because momentum is already removed by the incline position, there's little benefit to going heavier than you can curl with a slow, controlled tempo.
- Place it after your primary pulling exercises in a session, since strict-form biceps isolation work doesn't need to be done fresh the way a compound lift does.
- This isolation move recovers quickly, so training biceps two or three times a week is reasonable as long as total volume across the week stays sensible.
Safety notes
- Choose a lighter starting weight than you'd use standing, since the strict position removes any ability to cheat a rep up.
- Stop if you feel pinching at the front of the shoulder; that usually means the incline angle is too steep for your current shoulder mobility.

Frequently asked questions
How many sets and reps for incline barbell curls?
3 sets of 8 to 12 reps with a slow, controlled tempo is a solid default. Since the incline position already removes momentum, there's no need to chase heavier weight past what you can lift with strict form.
Can I do this curl with dumbbells instead of a barbell?
Yes. The dumbbell prone incline curl uses the same face-down position but lets each arm move and rotate independently, which some lifters find more comfortable on the wrists.
Why do my shoulders hurt during incline curls?
A steep incline angle can pinch the front of the shoulder for some lifters. Try a slightly shallower incline, or switch to a standing curl if the discomfort continues.
What's the point of doing curls lying against an incline instead of standing?
Standing curls let you lean back or swing your hips to move the weight, especially late in a set. The incline position pins your torso down so your biceps have to do all the work without any body english.
How much weight should I use compared to a standing curl?
Expect to use noticeably less, since your hips and back can no longer help swing the bar up. A weight that feels light standing is often about right lying prone against the incline.
