Barbell Curls Lying Against An Incline
Chest against an incline bench with the barbell hanging straight down, this curl removes every source of cheating: no hip drive, no leaning back, no swing. What is left is strict elbow flexion against a bar that is heaviest around the 90-degree mark and nearly weightless above it.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Set the bench to 45-60 degrees and lie face down along it, chest and the front of your shoulders on the pad.
- Let your arms hang straight down, perpendicular to the floor, so the bar sits under your shoulders rather than in front of them.
- Take a shoulder-width supinated grip on a straight bar, or the inner handles of an EZ bar if your wrists complain.
- Set the bench high enough that the plates clear the floor at full extension: with 10 kg plates you need about 30 cm underneath.
- Rest your forehead lightly on the pad and put your feet down for balance, not for pushing.
Every rep
Breathing & tempo — Exhale as the bar comes up, inhale as it lowers. One second up, a one-second squeeze, three seconds down. The slow eccentric is most of the point of a curl you cannot cheat.
Sets, reps & load
Where to start, and what to change when it stops being hard.
An empty 20 kg barbell is already a real set here for most people, and a 10-12 kg EZ bar is a fair start for a beginner. Add 2.5 kg only when every rep starts from a fully straight arm with your chest glued to the pad. If the bar swings up on the first rep of a set, the weight is wrong rather than the technique.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Keep the elbows pointing at the floor for every rep. If they swing forward you have turned the curl into a short row: drop 5 kg and reset the elbow position before each rep.
Raise the bench a notch so the plates clear the floor, then lower until the elbow is fully open on every rep. Pause for a count down there so you cannot fake it.
Treat shoulder height as the ceiling and spend the effort on a three-second lowering instead. Time under tension in the stretched half beats a squeeze against nothing.
Start at 60-70% of what you use standing. The bench support removes the leg and back contribution you did not know you were using.
Why bother
Standing curls fail for a boring reason: people lean back. Pinning your chest to an incline pad takes the hips, the lower back and the front delts out of the equation, so the only thing that can move the bar is your elbows bending. Loads drop by 20-30% and that is the honest number.
With your arms hanging vertically, the load on the biceps peaks near 90 degrees of elbow flexion and falls towards nothing as the bar arrives over your elbows. Curling higher than shoulder height feels like a squeeze but is unloaded. The useful work sits in the first two-thirds of the arc and in the lowering.
Where it fits
Late in an arm or pull session, after rows and chin-ups, in the 8-15 range. It pairs badly with other strict chest-supported curls in the same workout, so run one of them per session. Two sessions a week of direct elbow flexion covers most people.

Asked and answered
Is this the same as a spider curl?
Close, not identical. A spider curl uses a near-vertical bench so the arms hang free in front of the chest; here the bench sits at 45-60 degrees and your whole torso rests along it. The training effect is nearly the same, which is strict elbow flexion with no body English. Pick whichever bench angle lets your arms hang truly vertical.
Why can I lift so much less than on a standing curl?
Because a standing barbell curl quietly borrows from your hips, lower back and shoulders. Chest support removes all three. A 20-30% drop is normal and it is not a step backwards; you are finally loading only the muscle you meant to load.
Straight bar or EZ bar?
Straight bar if your wrists tolerate full supination, because holding supination is part of what the biceps does and it loads the muscle slightly more. Switch to the inner handles of an EZ bar the moment you feel it in the wrist or on the outside of the elbow. A pain-free set beats a marginally better one.
How do I get the bar into position without a training partner?
Stand the loaded bar on the floor under the head end of the bench, lie face down on the pad first, then reach down and pick it up with both hands from a straight arm. Do not climb onto the bench while already holding it, which is how people scrape a shin or drop a plate on a foot. Reverse it at the end: lower the last rep to a straight arm and set the bar on the floor before you get up.
