Pilates for rounded shoulders: what the posture is and isn't, the upper back and shoulder blades, what the evidence shows, and the classes to follow

Pilates alone hasn't been shown to move them

In three small trials that measured it in people with rounded shoulders, Pilates didn't change shoulder position, or changed it no more than standard posture exercise.

Sources 1, 2, 3

Common, and usually harmless

In one study, 73% of healthy adults had a rounded right shoulder and 66% a rounded left one. Shoulder-blade position doesn't reliably explain shoulder or neck pain.

Sources 4, 5, 6, 7

Strengthening changed posture; stretching didn't

Across 23 controlled trials, strengthening improved posture and stretching didn't. A 2026 review found corrective programmes built on rows, reverse flys and prone raises improved forward-shoulder angles over about 8 weeks, though pain and function didn't consistently improve; most of its trials were small and from one country.

Use Pilates as the frame, and add the strength work

The swan and swimming, plus prone Y, T and W raises, band rows and pull-aparts and the push-up plus, 3 days a week for at least 8 weeks. Chest stretches are optional.

Sources 9, 10, 11

There's no correct number

The usual tests give the same answer when one person repeats them, but have no validated normal value, and the old rule that a shoulder "more than 1 inch" off the table is rounded couldn't tell people with shoulder symptoms from people without.

Sources 12, 13

Know the warning signs

See a GP for "A new or increasing hunch, or height loss.", which in older adults can be a sign of a spinal fracture. Call 999 for "shoulder or arm pain with chest pain that feels tight or squeezing". The full list is below.

Forward, tipped and turned in

Rounded shoulders (forward shoulder posture) means the shoulder blades sit further forward around the ribcage, tipped forward and turned in. They often come with a forward head and a rounded upper back, but "Forward head posture, rounded shoulders, and increased thoracic kyphosis can exist alone or in any combination". "Upper crossed syndrome" is a label for all three together, which trials use to choose who takes part; it isn't a diagnosis. Our rounded shoulders guide has the full explanation.

Sources 17, 14, 9

Very commonEmerging evidence

In 88 healthy adults aged 20 to 50, 73% had a rounded right shoulder and 66% a rounded left one, judged against a plumb line. It's a common shape, not a disorder.

How they're measured, and why there's no targetStrong evidence

Lying on your back, the distance from the back of the shoulder to the table is reliable, but averaged about 6 cm in people with and without shoulder symptoms and ranged from 3 to 9.5 cm in people without. The textbook "more than 1 inch" rule flagged everyone without symptoms as well as everyone with them. The measures are reliable when the same person repeats them, and trials define their photo angles differently, so numbers can't be compared from one study to the next. Use a measure to track your own change, not to diagnose yourself.

Sources 12, 13, 18, 1, 2

The small chest muscle (pec minor)Emerging evidence

In 50 people without shoulder pain, those with a short pec minor had more upper-back rounding and inward-turned shoulder blades, and moved them in a way seen in shoulder impingement. But in 144 people, pec minor length wasn't linked to shoulder pain or disability.

Sources 19, 20, 21

Older adults: a rounded upper back

The upper-back curve grows with age, faster in women, and a large curve is linked with low bone mass and spinal fractures. The NHS says some older people develop a stooped posture, which happens "when the bones in the spine have broken", so a new hunch in an older adult belongs in the warning signs below, not in a posture class. Our Pilates for kyphosis guide covers the curve.

Sources 22, 23, 15

Shoulder pain: no consistent linkEmerging evidence

In shoulder impingement, shoulder-blade position was inconsistent across 10 studies, and the authors said rehabilitation to an "idealised normal posture is currently not supported". There was moderate evidence of no difference in upper-back rounding between people with and without shoulder pain.

Sources 5, 6, 21

Neck pain: a weak linkMixed evidence

In office workers, "shoulder posture was not correlated with neck pain", and in 1,108 Australian 17-year-olds, posture types weren't linked to neck pain or headache. A forward head goes with neck pain in adults in snapshot studies, which can't show cause.

Sources 7, 24, 25

What sitting tall does changeStrong evidence

Sitting upright lets you lift your arm higher straight away. Taping 60 people with shoulder impingement into a more upright posture raised the point at which the arm hurt, but not how much it hurt.

Sources 6, 26

Why the idea lasts

Physiotherapists still rate upright sitting as best "despite a lack of strong evidence", and a "large posture industry has flourished", as one viewpoint puts it.

Sources 27, 28

Strengthening changed posture; stretching didn'tEmerging evidence

Across 23 controlled trials in 969 healthy people, stretching programmes had no effect on posture, while strengthening programmes made large improvements, most in the upper back and neck. The authors rate the evidence against stretching as moderate certainty.

Source 8

Corrective programmes: posture improved, pain didn't consistentlyEmerging evidence

Khorramroo 2026 (28 trials, 901 people with upper crossed syndrome) found corrective exercise improved the forward-shoulder angle across 18 trials, with strengthening programmes doing about as well, but effects on pain, function and balance were inconclusive. Most programmes ran 8 weeks, 3 times a week. The authors rate the certainty for posture as moderate, but most trials were small and from one country (Iran), and results varied widely between them. An earlier review of 22 studies agreed.

Sources 9, 29

Single trials: swimmers, teenagers and young womenEmerging evidence

In 28 elite swimmers, 8 weeks of exercise reduced forward head and shoulder measures. In 130 teenagers, 16 weeks of strength and stretching in PE lessons improved head and shoulder angles, with no change in shoulder pain. In 39 young swimmers, 6 weeks of stretching and back-of-shoulder strengthening reduced the shoulder-to-wall distance by 9.6 mm, against 2.0 mm. In 60 young women, adding lower trapezius strengthening to pec minor stretching did better than stretching alone.

Sources 30, 31, 32, 33

The Pilates trialsEmerging evidence

In 45 girls aged 13 to 16 with upper crossed syndrome, 6 weeks of Pilates, 3 times a week, didn't change the rounded shoulder angle (62.5 to 61.9 degrees), while corrective exercise and the Alexander technique did. In 26 students, 12 weeks of Pilates improved head and upper-back angles but made no difference to the forward shoulder angle, a result the trial's summary leaves out. In 40 young women, rounded shoulders improved by a similar amount with Pilates and with standard posture exercise over 4 weeks.

All three were small: the first had unblinded assessors and was registered after it ran, and the third reports some results inconsistently. A registered trial comparing Pilates with yoga for rounded shoulders in 30 women finished in 2023 but has posted no results.

Sources 1, 2, 3, 34, 35

Other Pilates posture studiesMixed evidence

In 74 women, 6 months of Pilates improved shoulder levelness seen from the front, not rounding. Pilates improved head angles in some small trials, but not shoulder position against home exercise in 46 people. A 2024 review found very low to low certainty evidence that Pilates improves a "shoulder angle" in adults; we couldn't check which angle it means.

Sources 36, 37, 38, 39

Does it last?Mixed evidence

Barely studied. In 24 men, an 8-week programme cut the forward shoulder angle from 54.4 to 45.5 degrees, and it was 46.5 degrees 4 weeks after they stopped.

Source 40

Chest stretches: optionalEmerging evidence

A one-arm doorway stretch lengthened the pec minor most in a single session, but 6 weeks of daily stretching didn't change its resting length, and adding it to a 12-week shoulder programme gave no extra benefit in 80 people.

Sources 41, 42, 43

Strength isn't the same as positionMixed evidence

Shoulder-blade strength doesn't match resting shoulder-blade position, and in one trial the upper back became more upright after 6 weeks but "Resting scapular posture did not change". Exercise helps shoulder pain, but not by changing how the shoulder blades move.

Sources 44, 45, 46

Three days a week, for at least 8 weeks

Most programmes that changed shoulder angles ran 8 weeks, 3 sessions a week, and 6 to 12 weeks did about as well as each other. Do the shoulder-blade moves on 3 days a week, inside a Pilates class or on their own (our suggestion).

Sources 9, 30

Keep going

Only one trial checked whether the change lasted, and it held 4 weeks after stopping. Treat it like any strength: keep some of the work in your week (our suggestion).

Source 40

At a desk, strength matters more than set-upEmerging evidence

Two Cochrane reviews found workstation changes made little difference to arm, neck and shoulder pain, while strengthening the neck, shoulder and shoulder-blade muscles eased office workers' neck pain, at low certainty. Our Pilates for office workers guide has a 15-minute class by your desk.

Sources 47, 48, 49

The reformer

The rowing series, pulling straps, chest expansion and backstroke work the same muscles as the band moves. Start with a light spring, and arms below shoulder height if a shoulder is sore (our suggestion). The only reformer posture study had 22 office workers and no comparison group.

Source 50

With osteoporosis

The roll-down and curl-up moves' caution: "With osteoporosis, a UK consensus suggests, as a precaution, alternatives to the Pilates roll-down and curl-up; people who already move comfortably and smoothly can continue." Our Pilates for posture guide adds "With osteoporosis and a high fracture risk, leave out the spine twist and the mermaid." Back extension (the swan, swimming and the seated upper-back lift) stays in.

Source 23

Deep backbends

With back pain or spinal stenosis, keep the swan small, as its caution says, and leave out the swan dive and rocking.

Hypermobile joints

Keep chest stretches in the middle of the range rather than hanging in them (our suggestion, from our Pilates for hypermobility guide).

Long rounded positions

The roll-over, jack knife and open-leg rocker don't undo anything, but they shouldn't be the centre of a class about posture; keep them for strong, healthy backs (our suggestion).

Call 999

• Call 999: shoulder or arm pain with chest pain that feels tight or squeezing, or chest pain that spreads to your arms, neck or jaw, especially with shortness of breath, sweating or feeling sick. It could be a heart attack.
• Call 999 or go to A&E: new problems walking, loss of bladder or bowel control, or a sudden loss of coordination, such as difficulty doing up buttons. These can be signs of pressure on the spinal cord.

Get help from NHS 111

Get help from NHS 111: pain or tightness in your chest, neck, shoulders, jaw or arms that comes and goes, often brought on by exercise, stress, emotion or cold and easing after a few minutes' rest. It can be angina, a sign of a heart problem. If you've been diagnosed with angina, get help from NHS 111 too if it feels worse than before, is happening more often, lasts longer or happens when you're resting.

Get help the same day

• Same day (GP or NHS 111): sudden or very bad shoulder pain; you cannot move your arm; the arm or shoulder is badly swollen or has changed shape; pins and needles that do not go away; no feeling in the arm; the arm is hot or cold to the touch; pain that started after an injury such as a fall; or severe pain in both shoulders.
• Same day (urgent GP appointment or NHS 111): severe neck pain that starts suddenly or gets worse quickly; heaviness or weakness in the arms or legs; pins and needles in an arm along with neck or arm pain; or pain between the shoulder blades.
• Same day: clumsiness in your hands, or numbness, pins and needles or weakness in one or both arms, that is getting worse; problems with balance or walking since the neck pain started; or neck pain with a severe headache.
• Arm weakness or numbness that keeps getting worse, severe pain that painkillers and rest do not touch, or an unexplained fever.

A new hunch, height loss or sudden back pain

• Sudden new back pain after a minor fall, lift, cough or sneeze, from 50 or past the menopause, or if you take long-term steroid tablets; or height loss, a curved spine or a change in posture: see a GP. It can be a spinal fracture.
• A new or increasing hunch, or height loss.
• New back pain after a minor fall, bend, lift or cough: it can be a spinal fracture from osteoporosis, and not every spinal fracture hurts.
• Unexplained back pain, losing height or a back that is becoming more curved can be signs of a spinal fracture from osteoporosis, especially after 50. See a GP.
• Nerve problems with a spinal fracture need urgent specialist care.

Sources 23, 15, 14

See a GP or physiotherapist

• Pain that is getting worse or has not improved after 2 weeks of looking after it yourself, or it is very hard to move your arm. In many areas you can refer yourself to physiotherapy.
• No improvement after 6 weeks of exercise, or arm symptoms still there beyond 6 to 12 weeks.
• Nerve symptoms and trouble with daily life more than 3 months after an injury: a guideline advises referral for medical investigation.

Source 52

A child or teenager

See a GP if you think your child might have kyphosis. A curve can get worse until growth stops, and a stiff, sharp or painful curve that doesn't straighten when standing tall isn't a simple slouch. Rarely, a curve that keeps growing causes weakness, numbness or tingling in the legs, bladder or bowel changes, or difficulty breathing.

Source 14

Chest pain or fainting while exercising: call 999

Call 999 if:

• You get sudden pain or discomfort in your chest that doesn't go away; it can feel like squeezing or pressure, burning or indigestion.
• The pain spreads to your left or right arm, or your neck, jaw, stomach or back.
• You have chest pain and feel sweaty, sick, light-headed or short of breath.
• Someone faints while exercising, can't be woken within 1 minute, or has chest pain or a pounding, fluttering or irregular heartbeat.

Sources 16, 51

Unusual breathlessness

Call 999 or go to A&E (accident and emergency) straight away for severe difficulty breathing (gasping, choking or not able to get words out), a chest that feels tight or heavy, pain that spreads to your arms, back, neck and jaw, lips or skin turning very pale, blue or grey, or sudden confusion. If you're more short of breath than usual, or your heart is racing, fluttering or skipping beats, contact NHS 111.

Stop the session if

You feel any pain or become unwell, as the NHS advises for its Pilates videos, and especially for chest pain or pressure, unusual breathlessness, dizziness or fainting. If you have a health problem, an injury or any symptoms, get advice from a healthcare professional, such as a GP, before you start.

Before you start

The NHS advises getting advice from a healthcare professional first if you have a health problem, an injury or symptoms, or have recently had a heart attack or an operation.

"Rounded shoulders cause shoulder and neck pain"Emerging evidence

Shoulder-blade position in shoulder impingement is inconsistent, upper-back rounding doesn't differ with or without shoulder pain, and shoulder position wasn't linked with neck pain in office workers.

"Posture can be corrected in a few weeks"Emerging evidence

Trials ran 6 to 16 weeks, mostly 8, and only one checked whether the change lasted (4 weeks after stopping).

"Pilates fixes rounded shoulders"Emerging evidence

In three small trials, Pilates didn't change shoulder position or did no better than standard posture exercise. Strengthening programmes did change it.

Sources 1, 2, 3, 9

"Stretch your tight chest to open your shoulders"Emerging evidence

Stretching programmes didn't change posture, and 6 weeks of daily pec minor stretching didn't lengthen it.

"There's a perfect posture to aim for"Strong evidence

No validated normal value exists, the common table test flags people without symptoms too, and the upright sitting that physiotherapists rate as optimal lacks strong evidence.

Sources 12, 27

"You need a reformer to fix your posture"Strong evidence

The only reformer posture study had 22 people and no comparison group, and the trials that changed shoulder angles used bands, dumbbells and body weight.
