Barbell Prone Incline Curl

1. Set an incline bench to a steep angle and lie face down on it, chest against the pad.
2. Let a barbell hang straight down with an underhand (supinated) grip, arms fully extended.
3. Brace your core and keep your chest pressed into the bench.
4. Curl the barbell upward by bending your elbows, keeping your upper arms still.
5. Squeeze your biceps hard as the bar approaches shoulder height.
6. Pause briefly at the top of the curl.
7. Lower the barbell slowly back to a full arm extension.
8. Repeat without letting your shoulders round forward off the pad.

Common Mistakes

• Letting the shoulders round forward: Rounding forward off the pad to help lift the bar reduces the strict stretch this exercise is meant to provide. Keep your chest pressed into the bench throughout.
• Swinging the elbows forward: Elbows drifting away from the body shifts tension off the biceps. Keep your upper arms hanging steady and vertical.
• Using too much weight: A barbell too heavy forces you to jerk the weight up instead of curling with control. Choose a load you can lift with a smooth, strict motion.
• Cutting the bottom range short: Stopping before your arms fully extend limits the deep stretch that makes this variation effective. Lower the bar all the way down each rep.

Programming Tips

Place the prone incline curl late in a pull or arm session, after rows, chin-ups or heavy standing curls. Run 3 to 4 sets of 8 to 12 reps with a two to three second lowering phase; with the chest pinned to the pad it is a strict hypertrophy movement, not a strength builder.

Set the bench at 60 to 75 degrees so the bar hangs straight down. Most lifters start with a 10 to 15 kg fixed barbell; add 2.5 kg once every set hits 12 clean reps. The most common fault is the shoulders rolling forward off the pad to get the bar moving. Fix it by dropping the load, pressing your sternum into the bench, and starting every rep from a dead hang.

Common Questions

Is the prone incline curl the same as a spider curl?

Yes, both names describe a curl performed face down on an incline bench with the arms hanging vertically. Some gyms use spider curl for the version done on a preacher bench, but the mechanics are nearly identical.

How much weight should I use for prone incline curls?

Expect to curl roughly 50 to 60 percent of your standing barbell curl, so a lifter who curls 30 kg standing would use 15 to 20 kg here. The upper arms sit in front of the body and there is no leg or hip drive, so the biceps alone move the bar.

What is the difference between a prone incline curl and a regular incline curl?

The regular incline curl is done lying on your back with the arms behind the torso, which stretches the long head of the biceps. The prone version puts the arms in front of the body, which shortens the long head and emphasizes the peak contraction and the short head.
