Shoulder Pain During Bench Pressing: Biomechanical Root Causes and Grip Adjustments

Front shoulder pain on the bench is usually a setup problem before it is a body problem. The four things I would check first are your elbow flare, your shoulder blade position, where the bar touches your chest, and how wide your grip is. This article is part of our complete chest training guide, and it is about the shoulder pain bench press fix that most lifters actually need: small, specific changes you can test next session.

One honest caveat up front. I cannot diagnose your shoulder from a screen, and the research here is thinner than the gym folklore suggests. Treat everything below as a set of reasonable experiments, not guaranteed cures.

Why does my front shoulder hurt when I bench press?

The bench press loads the shoulder at its most vulnerable moment: the bottom, where the upper arm is stretched back and the bar wants to pull your joint forward. A 2024 narrative review describes a high risk of shoulder injury with this lift in powerlifters, but notes that the injury findings often say little about what the shoulder joint is actually doing during the press (Motlagh and Lipps, 2024).

So we work with what the biomechanics studies do tell us. A 2024 lab study put 10 experienced strength athletes through 21 bench press variations (different grip widths, elbow angles and shoulder blade positions) and used a musculoskeletal model to estimate forces inside the shoulder (Noteboom et al., 2024). Two findings matter for you. Grips narrower than 1.5 times the width between your shoulder bones lowered compression at the acromioclavicular joint. And pulling the shoulder blades back (as did the narrower grips) lowered posterior shear force at the main shoulder joint and rotator cuff activity. The team also found that how hard each lifter pushed the bar outward or inward varied a lot between people and strongly affected shoulder forces.

That is a model estimate in ten experienced lifters, not a trial in people with pain. Useful direction, not proof.

Cause 1: Flared elbows

Flaring means your upper arms sit close to 90 degrees from your torso, so your body and arms form a “T”. It feels strong because the chest is stretched, but it also puts the shoulder in a tight, exposed position at the bottom.

The usual coaching fix is to tuck the elbows to roughly 45-60 degrees, forearms close to vertical under the bar. A fair warning: Noteboom’s team tested abduction angles of 45, 70 and 90 degrees, but their published summary reports results for grip width and shoulder blade position, not a clear effect of elbow angle. So the study does not prove the tuck. It is a sensible starting point based on joint position, not a studied threshold.

In the gym, this looks like elbows shooting out the moment the bar gets heavy. Drop the weight, take a slower descent, and think about bending the bar rather than pulling it apart.

Cause 2: Loose shoulder blades

If your shoulder blades slide forward as the bar comes down, your upper back stops supporting the press and the front of the shoulder takes more of the work. This is the factor with the most direct support here: retraction lowered estimated posterior shear force and rotator cuff activity in the 2024 model (Noteboom et al., 2024).

The fix is simple, though not always easy:

• Lie down and pull your shoulder blades back and down, like squeezing a pencil between them.
• Keep your chest up and your upper back pressed into the bench.
• Do this before you unrack the bar. Not during the rep. Before.

A bench with a lot of padding can make it harder to hold the position. A firm flat bench helps most people.

Cause 3: A touch point too high on the chest

When the bar lands near your collarbone or neck, your elbows almost have to flare to get there. The shoulder ends up in a position that many lifters find irritating.

Aim for your lower chest or sternum, roughly in line with the bottom of the pecs, with the forearms vertical when the bar touches. Film a set from the side. If your forearms lean toward your feet or toward your head at the bottom, the touch point is off.

I am not aware of a trial that tests touch point against pain, so this one comes from coaching logic and joint position, not a study.

Cause 4: A very wide grip

Wide grips are popular because they shorten the bar path and can raise your one-rep max. In a study of 14 bench-trained men, the wide and medium grips produced the greatest horizontal shoulder moments compared with the narrow grip, and the authors suggested a wide or medium grip could help lifting as much as possible in a 1-RM (Larsen et al., 2020). That is a performance finding. It tells us why lifters drift wide, not that wide is safe for a sore joint.

For shoulder comfort, the modeling study points the other way: grips under 1.5 times biacromial width were linked to lower acromioclavicular compression, which the authors say may reduce the risk of distal clavicular osteolysis (Noteboom et al., 2024). If your hands sit beyond your shoulder width plus a lot, test pulling them in a hand-width or two. For more on grip and pec versus triceps emphasis, see our bench press grip width breakdown.

What about arching?

A moderate arch is common in powerlifting and often gets criticized online. In a 2022 study of 20 experienced male lifters, the arch technique raised latissimus dorsi activation, while the standard technique produced integrated shoulder moments that were 8% larger (Cudlip et al., 2022). The lifts were done at 25%, 50% and 75% of their self-reported 1RM, so this does not cover maximal loads, and the study did not test people with shoulder pain.

So a small, comfortable arch with your chest up and blades pinned looks reasonable. An extreme arch is a skill, not a shoulder fix. For the full comparison, see bench press arch: powerlifting versus bodybuilding.

The setup sequence that ties it together

Run through it on every working set, including your first light one. Habit beats cleverness here.

Swap options while it settles

You do not have to stop training chest. You may just need a different tool for a few weeks. This is the short version; our guide to training around shoulder pain goes through each swap in depth.

• Neutral-grip dumbbell press. Palms facing each other lets the elbows tuck naturally. Many lifters find it kinder, though I know of no trial proving it heals pain. See the incline dumbbell press angle comparison.
• Floor press. The floor limits how far back the elbows travel, which is why people use it during shoulder issues. Read more in our floor press guide.
• Machine presses. Fixed paths let you control the load and range. A cable or machine can be a useful backup, though a 2022 motion-capture study noted that cable pulley exercises produced larger shoulder moments than bench press at the loads tested, so “easier on the joint” is not automatic (Schütz et al., 2022).

Cut the load by roughly 10-20% and use a rep range you can finish with clean reps and 2-3 reps in reserve. The RIR/RPE calculator can help you pick loads. A narrative review also suggests autoregulation methods (RPE, velocity) over grinding to failure for lowering overexertion risk in experienced powerlifters (Motlagh and Lipps, 2024).

Does strengthening the shoulder help?

Possibly. For people with subacromial pain syndrome, a 2024 meta-analysis of 8 randomized trials with 387 participants found scapular stabilization exercises gave greater improvements in pain (visual analog scale) and function than conventional physical therapy, but no better range of motion; the authors rate the evidence as moderately supportive and call for better trials (Zhong et al., 2024).

A 2025 network meta-analysis of 15-16 trials found concentric strengthening ranked best for pain and function in rotator cuff-related shoulder pain. For function, it and other strengthening types beat motor control and scapula-focused training, though most head-to-head comparisons for pain were not statistically significant (Zhang et al., 2025). That conflicts a little with the first review. The likely reason is different comparison groups: one pitted scapular exercises against usual physio, the other ranked seven exercise types against each other. Either way, exercise looks useful, and the specific best type remains unsettled.

A Danish sports physiotherapy statement paper found a rehabilitation programme that included strengthening had a large effect on pain and disability versus no treatment in athletes with subacromial impingement, but graded the evidence as very low to moderate quality (Liaghat et al., 2023). Translation: exercise is worth doing, ideally guided by someone who has examined your shoulder.

Add rows and face pulls into your week, which also fits well with a balanced push and pull plan. See our free workout plans for a structure with enough back work.

A short warm-up that is worth the 3 minutes

I do not know of strong evidence that a particular warm-up prevents bench press shoulder pain, so think of this as cheap preparation:

1. 1-2 minutes of light band pull-aparts or external rotations.
2. 5-10 slow reps with the empty bar, practicing the blade position.
3. 2-4 ramp-up sets, each a bit heavier, with the same setup every time.

When to stop and see a doctor

Do not push through pain that:

• started with a sudden pop or tearing sensation
• comes with bruising, visible deformity or arm weakness
• includes numbness, tingling or pain down the arm
• wakes you at night
• is not improving after 2-3 weeks of reduced load and cleaner technique

Chest muscle injuries and other structural problems can look like “just a sore shoulder” at first. A physiotherapist or sports doctor can examine the joint, which no article can do. If you want help programming around an injury, check our training volume calculator for a sensible weekly load while you recover, and use the parent chest training guide to rebuild your session structure.

The bottom line

Start with the shoulder blades, then the touch point, then the elbow tuck, then the grip. Keep the weight lighter for a couple of weeks, use dumbbells or a floor press if the barbell still bites, and add pulling and rotator cuff work.

If the pain does not respond, or any red flag shows up, stop and get it examined. Pushing through it is how a two-week annoyance becomes a six-month problem.
