Is Overhead Press Bad for Shoulders? The Impingement Myth Explained

Is overhead press bad for shoulders? For most healthy lifters, no. Nothing in the research shows that pressing overhead with sound technique wears out the rotator cuff, and the fear of “pinching” the tendon rests on an idea that has not held up well under direct testing.

That does not mean every press is safe for every shoulder. Technique, load and your own history matter. This article sits inside our joint-friendly lifting myth-busting guide, and it covers the mechanics: what the shoulder blade does, what “impingement” really means, and which versions of pressing and pulling deserve a bit more caution.

What happens in your shoulder during an overhead press

Your shoulder is not one joint. It is a team: the upper arm bone (humerus) sits in the socket of the shoulder blade (scapula), and the scapula glides on your rib cage. When your arm goes overhead, both parts move together. Researchers call this coordinated movement scapulohumeral rhythm.

Over the top of the joint sits a bony roof called the acromion. Under that roof run the rotator cuff tendons, mainly the supraspinatus. The old story was simple: lift your arm, the roof comes down, the tendon gets squeezed. Hence “impingement.”

Reality is more interesting. A review of shoulder rehabilitation exercises reports that during maximum arm elevation the scapula normally rotates upward by about 45-55 degrees, tilts back and turns outward. The serratus anterior, working with the upper and lower trapezius, drives this (Escamilla et al., 2009). As the blade rotates upward, the roof moves up and out of the way.

Does overhead pressing cause impingement?

Short answer: there is no good evidence that it does in healthy shoulders. Here is what the better studies show.

A 2019 fluoroscopy study tracked 40 people while they raised their arms in the scapular plane. Participants with lower scapular upward rotation had a normalized minimum distance between the bony arch and the rotator cuff insertion that was 34.8% smaller with the arm at the side. The distances were generally smallest below 70 degrees of elevation, and contact between the arch and the tendon happened in 45% of participants. The authors concluded that rotator cuff compression may be less common than traditionally presumed (Lawrence et al., 2019).

Read that carefully. The tight zone is lower in the arm’s range, not at the top where you lock out a press. Weak upward rotation shifts the risky zone to lower angles. And even then, contact was not universal. This was a lab study of 40 people, so it shows a pattern, not a verdict on your shoulder.

A second study looked at 40 people without pain, half with obviously abnormal shoulder blade motion and half with normal motion. The gap under the bone at 45 and 90 degrees of active elevation did not differ between the groups (Seitz et al., 2012). When the researchers manually helped the blade rotate up and tilt back, the gap increased in both groups. So blade position does influence the space, but messy-looking motion by itself did not shrink it.

Why the word “impingement” is losing ground

Even clinicians who treat shoulders have been moving away from the picture of a tendon being pinched. One reason is a big surgical trial.

In the CSAW trial, 313 UK patients with subacromial shoulder pain (at least 3 months, intact rotator cuff, previous non-operative care) were randomly assigned to decompression surgery, a placebo “look inside only” arthroscopy, or no treatment. At 6 months, the Oxford Shoulder Score did not differ between the two surgical groups (32.7 versus 34.2 points). Both beat no treatment slightly, but not by a clinically important amount (Beard et al., 2018).

Pause on what that means. If shaving bone to make more room does no better than a sham operation, then “not enough room” cannot be the whole explanation for the pain. Many clinicians now use the broader label rotator cuff-related shoulder pain. It admits what we know: the shoulder can hurt, the tendon can be irritated, and the cause is usually a mix of load, capacity and sensitivity rather than a simple pinch.

Do I need perfect scapular control to press safely?

No. This is where gym advice goes overboard. You will hear that any “winging” or uneven blade means you must not press until a physio signs off.

A 2023 systematic review pooled 34 studies and 2,365 people. Scapular dyskinesis, an abnormal-looking shoulder blade pattern, appeared in about 48% of people without shoulder symptoms and about 60% of people with them. The authors suggest it may be a normal finding in nearly half of asymptomatic people (Salamh et al., 2023). They also note that studies measured it inconsistently.

Practical read: if your shoulders feel fine and your pressing strength climbs, an asymmetrical blade is not an emergency. If you have pain, the pattern may be worth addressing with a clinician, but it is one piece of the puzzle.

Scapular rhythm in the gym: what it should look like

You do not need to think about every degree. You need to avoid the things that block the blade from doing its job.

• Let the blades rotate up. At the top of the press a gentle upward shrug is fine and natural. Pinning your shoulder blades down and back for the whole rep is a common “cue” that works against upward rotation.
• Keep the ribs down. A big back arch makes it look like you are getting more overhead range, but you are borrowing it from the lower back, not the shoulder.
• Stay in the plane that suits your shoulder. Pressing with the arms slightly in front of the body, roughly in the scapular plane, is the position most lifters find comfortable. It is also the plane most shoulder studies use for arm elevation, including the fluoroscopy work above.
• Use controlled reps. A review of rehab exercises notes that when weakness, fatigue or abnormal firing patterns disrupt normal shoulder blade motion, the shoulder works less efficiently and injury risk rises (Escamilla et al., 2009). Grinding your last reps with a tilting torso is how technique degrades.

In the gym, the most common mistake here is rushing the rep, bouncing out of the bottom and leaning back until the press becomes an incline press for the upper chest. Slow it down.

Upright rows, behind-the-neck presses and wide pulls: different risk profiles

Overhead pressing in a normal front position is one thing. Some exercises ask the shoulder for more.

Behind-the-neck press and pulldown. These use the so-called “high-five” position, with the upper arms out to the side and rotated back. In a study of 123 weight trainers and 36 non-lifting controls, the weight-training group showed more clinical signs of anterior shoulder instability and hyperlaxity. The performance of behind-the-neck pulldowns and military press was associated with those signs, while external rotator strengthening showed an inverse association (Kolber et al., 2013). The design was cross-sectional, so it cannot prove those lifts caused anything. It does show why many coaches default to the front position.

Wide-grip pulling overhead. A small motion-capture study of 11 people who regularly did pull-ups found that wide and reverse-grip pull-ups produced kinematic patterns the authors linked with increased subacromial impingement risk, and that high arm elevation reduces the subacromial space (Prinold et al., 2016). Eleven young people, no injury outcomes: treat it as a flag, not proof.

Upright rows. I could not find a trial that tests the upright row directly. The caution is a reasoned one: it takes the elbows high with the arms internally rotated, and the rehab review notes that internal rotation of the arm and anterior scapular tilt decrease subacromial space and increase impingement risk in the “empty can” position compared with “full can” (Escamilla et al., 2009). That is an inference, not a proven harm. If your shoulders dislike them, lateral raises are an easy swap, and our upright row modifications guide covers safer setups.

Exercise	Arm position	Relative demand on the shoulder	Simple swap
Front barbell or dumbbell press	In front of body, near scapular plane	Lower, if technique is controlled	Keep it
Landmine press	Angled forward, less overhead	Lower	Good for stiff shoulders
Behind-the-neck press	Arms out to the side, rotated back	Higher, needs good mobility	Front press
Upright row	Elbows high, arms internally rotated	Higher (reasoned, not trialled)	Lateral raise, face pull
Wide-grip pulldown or pull-up	Arms high and wide	Moderate to higher	Neutral grip or close grip

Who should adjust the overhead press

The research here is solid on mechanics but limited on individual cases. Some lifters will need modifications:

• Limited overhead mobility. A stiff upper back or tight lats forces you to lean back to get the bar overhead. Use a landmine press or a high-incline dumbbell press instead.
• Known structural issues. A marked kyphosis or bony spurs identified on imaging can change which angles are comfortable. This is where a clinician’s advice beats general rules.
• Current shoulder pain. Pressing is not automatically off limits, but it needs a proper plan. A 2017 meta-analysis of trials in people with shoulder impingement found exercise was better than non-exercise controls for pain, though the authors rated the evidence as very low quality (Steuri et al., 2017).

The overhead press checklist

1. Ribs down, glutes tight. Brace like a plank. No big arch.
2. Elbows slightly in front. Not flared straight out to the sides.
3. Bar path. Press up and slightly back so the bar finishes over the middle of your foot, with your head moving through.
4. Finish with a gentle shrug. This lets the shoulder blades rotate upward.
5. Load you can control. 6-12 reps with 1-3 reps in reserve. Our RIR and RPE calculator helps pick the load.
6. Pain check. Sharp or pinching pain means stop and change the angle, or get it assessed.

What if I get pain pressing overhead?

Pain is a signal, but it is not a diagnosis. Shoulder pain has many possible sources, and I cannot tell you which one you have. Reasonable first steps:

• Reduce the load and range to what is pain-free, for example a smaller press range or a landmine press.
• Keep training the shoulder, because rest alone rarely builds capacity.
• Give changes 2-3 weeks. If there is no change, it is time for an assessment.

See a doctor or physiotherapist promptly if you have pain at night, sudden loss of strength, numbness or tingling down the arm, a shoulder that feels like it is slipping out, or pain after a fall. Do not self-diagnose from the internet.

Bringing it together

The idea that overhead pressing ruins the rotator cuff is a myth in its simple form. The shoulder blade is built to rotate upward, imaging work suggests the tendon is contacted less often than assumed, and a placebo-controlled surgical trial undermined the “not enough room” model.

What remains is common sense. Keep your ribs down, let the blades rotate, choose loads you control, and treat behind-the-neck, upright and wide-grip work as optional extras with more demanding positions.
