Behind-the-neck press: the setup, what changes from the front press, and the shoulder range it asks for

The behind-the-neck press is an overhead press in which the bar starts and finishes behind your head, at the base of your skull, instead of at the top of your chest. Both studies on this page did it seated on a bench with an upright backrest and a barbell, and both put it beside the front press in the same people.¹²

This page covers the setup, what those studies measured against the front press, the shoulder range the position takes, the faults, and the sets. The standard press, with the bar in front, is on overhead press form, and the shoulder day around it is on the shoulder workout.

How to do the behind-the-neck press

1. Sit on a bench with an upright back. Both studies used a backrest set at 80 degrees; for the behind-the-neck version the trunk sat at 90 degrees so the bar could pass behind the head, with the lower back still supported.¹² A rack or a spotter puts the bar on your upper back.
2. Set your grip. Both studies set the hands so that the elbow made a 90-degree angle when the upper arm was at 90 degrees, level with the floor.¹² For the front press, the same studies put the hands just outside the shoulders.
3. Start below the back of your head. The bar began just below the bony bump at the base of the skull.²
4. Press to straight arms. The bar went up to full elbow extension in a roughly straight line, where the front press follows a curved, C-shaped path around the face.¹²
5. Lower under control to the same start point. The studies used two seconds up and two seconds down, with a pause of about half a second at the top.¹²

Behind-the-neck press vs front press: what was measured

Two studies from the same research group tested both presses in the same people and measured muscle activity with sensors on the skin (EMG):

• 8 male competitive bodybuilders, about 30 years old with about ten years of training, did six reps at 80% of their max on each press.² Their one-rep max was about 82 kilograms on the front press and about 76 behind the neck.
• 14 resistance-trained men, about 25 years old with at least three years of training, did four reps with their eight-rep max on each press. That load averaged 36.8 kilograms in front and 33.2 behind the neck.¹

Where the two agree:

• More rear-shoulder activity behind the neck. The bodybuilders showed it on the way up and on the way down;² the 14 men showed it on the way down only.¹
• More chest activity in front. The upper chest was more active in the front press in both studies, on the way up and on the way down.¹²

Where they disagree:

• The side of the shoulder. The bodybuilders showed more side-shoulder activity behind the neck in both phases;² the 14 men showed no difference.¹
• The front of the shoulder. In the bodybuilders it was about the same on the way up and higher behind the neck on the way down;² in the 14 men it was higher in the front press in both phases.¹
• The triceps and the upper traps. On the way down, the bodybuilders' triceps were more active in the front press and their upper traps showed no difference;² the 14 men had more triceps and upper-trap activity behind the neck.¹

Both were single-session measurements, not training studies, and muscle activity on the day is not muscle growth over months. The bodybuilders' study notes its sample is small and its results shouldn't be extended to other groups or to women without caution, and that it recorded no movement data.² The 14-man study notes that the front press usually moves through more range than the behind-the-neck press, which can change the comparison.¹

The shoulder range it asks for

A third study filmed 33 people pressing seated, in front of and behind the head, with three-dimensional motion capture, and also measured how far each shoulder moved when it was moved for them, without effort.³ What it recorded:

• The shoulders stayed inside that measured range in every measure but one: outward rotation of the shoulder in the men pressing behind the head.³
• The upper back started less extended in the behind-the-head press than in the front press, and the authors describe the two presses as starting from different spine positions.³
• The men and the women differed: the men kept a flat or normal curve in the lower back, while the women tended to round.³

The 14-man study's authors write that the behind-the-neck press asks for more shoulder mobility, and that someone short of it may need extra movements to get the bar behind the neck. They suggest getting used to the position and starting with very light loads.¹

A practical check, not a finding: sit upright against the backrest with an empty bar or a broomstick. If you can't lower it to the base of your skull without pushing your head forward or arching away from the pad, use the front press or the dumbbell shoulder press instead.

Barbell or machine

The bodybuilders also pressed on a shoulder press machine, with a front grip and a wide side grip. The machine allowed more weight (one-rep maxes of about 95 kilograms in front and 87 with the side grip) and drew less side- and rear-shoulder activity than the barbell. The authors read that as the barbell needing more work to keep its path steady.² No study of a Smith machine behind-the-neck press was found for this page.

The common faults, and a fix for each

• Pushing the head forward to clear the bar. If the bar only fits behind your head that way, the position is past the range you have today; go back to the front press.
• Lowering further than the base of the skull. The studies started there; stop there.
• Leaning off the backrest. Keep your back against the pad, as the studies did.
• Loading it like your front press. In both studies the behind-the-neck press was the lighter lift. Start well below your front press weight.
• Pressing through pain. If you have pain, an injury or a medical condition, stop and ask a doctor or a physical therapist.

Sets, reps and where it goes

• What the studies used: six reps at 80% of the one-rep max,² and four reps with the eight-rep max.¹ Those were test sets, not training plans.
• As a practical start: 3 sets of 8 to 10 with a light load, two or three reps short of failure, in place of the front press or after it on a shoulder day. This is practical advice, not a finding.
• Keep the side and the rear covered. Whatever press you use, lateral raises and a reverse fly train the side and the back of the shoulder directly.

Common questions

Is the behind-the-neck press better than the front press?

Neither study names one as better; both sets of authors say the two presses are not equivalent. Both measured more rear-shoulder activity behind the neck and more chest activity in front, and both found the front press the heavier lift.¹² They disagreed on the front and the side of the shoulder. No training study compared what the two build over weeks.

Can you do it standing?

Every study here was seated with the back supported, so this page doesn't describe a standing version. Standing presses are on overhead press form and the push press.

Does it need more shoulder mobility?

The 14-man study's authors say it does, and in the 33-person motion study the one measure outside the shoulders' own range was outward rotation, in the men pressing behind the head.¹³ Use the empty-bar check above before you load it.

If you'd rather not plan it alone

The press is one exercise; deciding whether it replaces your front press or sits beside it, and how it shares a week with your bench, is the part a page can't do. Coaching is the version where your workouts live in Trainerize, built around the days you actually have, and a weekly call looks at the week you just had and rebuilds the next one. Coaching to build muscle explains how that works, and here's how to apply. Otherwise: do the empty-bar check at your next shoulder session and write down what you find.
