What muscles does the close grip bench press work?

The triceps do most of the work. The chest is still involved, and the split is interesting: narrowing the grip lowered activity in the main body of the chest but raised it in the upper chest. Your front delts assist.

How close should your grip be on a close grip bench press?

About shoulder width. Narrower than that starts working against you, because it bends the wrists sideways, reduces the weight you can control and shortens the range, all of which mean less triceps work rather than more.

Why do my wrists hurt on close grip bench?

Almost always because the grip is too narrow, which forces the wrists out of line with the forearms. Widen to shoulder width and stack the wrists directly over the elbows. If something hurts and keeps hurting, that is a question for a physiotherapist.

Is close grip bench press a chest or triceps exercise?

Both, with the balance tipped toward the triceps. The measurements show the chest still working, with the upper portion actually more active than on a wide grip. Treat it as a triceps-biased chest press rather than a triceps isolation exercise.

Why is my close grip bench so much weaker?

Because a narrow grip gives your elbow a longer lever to overcome. It is a structural difference, not a weakness you are going to train away, and the gap between your two bench numbers stays roughly where it is.

Should your elbows be tucked on a close grip bench?

Closer to your body than on a standard bench, but not clamped against your ribs. Both extremes are documented as causing shoulder trouble. The grip is what makes the exercise, not how hard you squeeze your arms in.

Barbell close grip bench press

Also called Narrow grip bench press, CGBP, Close grip press, Close grip bench.

The short answer

The close grip bench press is a flat bench press with your hands about shoulder width instead of wide. Narrowing the grip gives your elbows more work to do and your shoulders less, so your triceps become the muscle driving it. Your chest does not stop working, it changes which part of it works. Expect to press less weight than on your normal grip, and expect that to be permanent.

How to do it

Step oneLie flat on a bench and grasp the barbell with a grip shoulder-width or slightly narrower apart.
Step twoUnrack the bar and hold it directly above your chest with arms fully extended.
Step threeSlowly lower the barbell to your lower chest, keeping your elbows close to your sides.
Step fourPause briefly at the bottom, then press the bar back up to the starting position.

What usually goes wrong

Each starts with what you would notice.

Your wrists ache and the bar feels wobbly.

WhyYour hands are too close together. A very narrow grip bends the wrists sideways under the bar, and once they are out of line nothing above them is stable.

FixMove out to about shoulder width. Hands touching in the middle of the bar is not the advanced version, it is the version that makes your triceps work less because you cannot hold as much weight or move it as far.

The bar path feels like it is fighting you on the way up.

WhyYour wrists are behind or ahead of your elbows rather than stacked on top of them, so part of every rep is spent correcting the line.

FixSet the wrists directly over the elbows before you unrack and keep them there. This is easier to hold with a slightly wider grip, which is another reason too narrow works against you.

Your shoulders feel pinched even though you are tucking hard.

WhyThe elbows are pinned tight against your ribs. Both extremes cause trouble here, flared square out and glued to the sides.

FixLet the elbows sit somewhere in between, closer to your body than on a normal bench but not touching it. Close grip is about hand spacing, not about clamping your arms shut.

You can press far less than on your normal bench and it feels like a step backward.

WhyNothing is wrong. A narrower grip gives your elbow a longer lever to work against, so the same triceps produce less on the bar.

FixTrack it as its own lift with its own numbers rather than comparing it to your regular bench. The gap is structural and it does not close.

Close grip or standard grip bench press

This has been measured across grip widths, expressed against the width of your own shoulders. Coming in from a wide grip to roughly shoulder width raised triceps activity and lowered activity in the main body of the chest. That much matches what everybody assumes.

The part that gets left out is the rest of the chest. In the same body of work, the upper chest was more active with the hands narrow, not less. So a close grip does not switch the chest off, it moves the work from the lower and middle of the muscle toward the top of it.

Close grip is a triceps-biased chest press. If you have been using it as a triceps isolation exercise and doing chest separately, you have been double counting.

Close grip bench or skull crushers

Both are triceps work and they do different jobs. A close grip bench is a whole-body press, so your legs, back and chest all contribute and you can load it far heavier than any isolation exercise.

A skull crusher takes everything else out and asks the elbow alone. The weight is a fraction of what you can bench, and that is the point.

The bench press version is where the strength is built. The isolation version is where the triceps is loaded through more of its length. There is no conflict between them and most sessions have room for one of each.

Closer is not better

The claim to argue with is that closer is better. It is not. Every source that has looked at it says the same thing: hands close together forces the wrists sideways, cuts the weight you can handle, makes the bar less stable and shortens the range. Those are four ways of training the triceps less while feeling like you are training them more.

The second claim to drop is that this replaces your chest work. The upper chest was more active with a narrow grip in the research, which means you are still pressing with your chest, just a different part of it.

What it does well is give you a way to load the triceps with real weight in a movement your whole body supports. That is genuinely different from anything you can do with your arms alone, and it is the reason it belongs in a program.

What it is for

The barbell close grip bench press is a compound pressing exercise that shifts emphasis onto the triceps by using a narrower grip. It also engages the pectorals and front delts, making it a popular movement for building arm and upper body pressing strength.
