Rounded Shoulders and a Hunched Upper Back: How Pilates Can Help
By Katherine, Lead Instructor, Certified Pilates Instructor · Last updated: September 2026
Pilates can help with the common, flexible kind of rounded shoulders and upper-back rounding — the kind caused by habit and muscle imbalance — by building strength through the mid-back and shoulder blades while gently opening a tight chest. Small studies show short-term improvement in postural angles with supervised training. Pilates does not reverse a rigid structural kyphosis (such as Scheuermann's disease) and is not a substitute for medical assessment.
Key takeaways
"Rounded shoulders" usually describes postural, flexible rounding — different from structural kyphosis, a fixed curve that needs medical evaluation.
Rounding is typically linked to sustained forward postures (desks, phones, driving) that tighten the chest and weaken the mid-back.
Pilates targets thoracic extension, shoulder-blade stabilization and chest opening; evidence shows short-term postural improvement, not a permanent fix.
In older adults, a hunch that is new or worsening can be linked to osteoporosis and vertebral fracture, so it deserves medical attention.
Change takes consistency — Pilates works best as an ongoing practice, not a one-time correction.
Postural rounding or structural kyphosis: what's the difference, and when should you see a doctor?
"Kyphosis" simply means the natural forward curve of the upper back — everyone has some. The term becomes a concern when that curve is exaggerated. Orthopaedic sources distinguish two broad patterns. Postural kyphosis is flexible: the spine itself is a normal shape, the rounding comes from habitual slouching, and a person can consciously straighten it. Structural kyphosis, most often Scheuermann's disease in adolescents, involves vertebrae that have actually developed a wedge shape over several levels, creating a rigid curve that cannot be undone by standing up straighter (OrthoInfo, AAOS).
See a doctor if you notice a visibly prominent or sharp curve (rather than a smooth one), a curve that keeps progressing, pain that is persistent or focused at one level of the spine, or any numbness, tingling or weakness in the legs (OrthoInfo, AAOS). In older adults, a curve that appears or worsens relatively suddenly warrants medical attention too, since it can signal a vertebral compression fracture (more on this below). Our team can adapt Pilates sessions around a diagnosis like this, working alongside your physician or physiotherapist, but we do not diagnose or treat structural spinal conditions ourselves.
If you're curious how Pilates fits into posture more broadly, our pillar guide on Pilates and posture covers what the method can and can't realistically do.
Why do your shoulders round in the first place?
For most people, rounded shoulders develop gradually from posture, not from a single incident. Hours spent leaning over a laptop, phone or steering wheel put the chest muscles (pectoralis major and minor) in a shortened position and leave the muscles between the shoulder blades — the mid and lower trapezius and rhomboids — under-used and comparatively weak. A 2026 narrative review of this "upper crossed" pattern in office workers describes exactly that combination: tightness through the chest and upper trapezius paired with weakness in the deep neck flexors and mid/lower trapezius, producing forward-rounded shoulders and a forward head (Russin, Robertson & Montalvo, 2026, IJERPH).
Rounded shoulders and a forward head often show up together, since both relate to sustained forward-leaning postures. We cover the forward-head piece — sometimes called "tech neck" — in a dedicated post; this article focuses on the upper back and shoulders. Long stretches of desk work are one of the biggest contributors, which we look at in more depth in our guide for desk workers.
How does Pilates approach rounded shoulders and a hunched upper back?
Pilates work for this pattern generally has three aims:
Thoracic extension — mobilizing and strengthening the upper back so it can move into (and hold) a more upright position. Exercises like a supported spine extension or gentle backbend on the reformer or mat train this directly.
Shoulder-blade stabilization — strengthening the mid and lower trapezius, rhomboids and serratus anterior so the shoulder blades sit against the ribcage instead of winging forward, using resistance work with the arms.
Chest opening — mobility and light stretching work for the pectoral muscles and front of the shoulder, so the shortened side of the imbalance isn't left unaddressed.
A 2024 systematic review looking at Pilates and posture found associated improvements in specific measurements — including thoracic kyphosis angle and forward head posture — after programs typically running 50–60 minutes, twice weekly. The certainty of this evidence is low: the included trials were small and varied in how they measured posture, and almost none followed participants after the program ended (Li et al., 2024, Archives of Rehabilitation Research and Clinical Translation). That supports short-term, supervised improvement in specific postural angles — it does not show that Pilates durably changes someone's habitual standing posture once training stops.
A caution for older adults: could a worsening hunch be linked to osteoporosis?
In older adults, an increasingly rounded upper back — sometimes called age-related hyperkyphosis — is common, affecting an estimated 20–40% of older adults, and it is not always caused by vertebral fractures (Katzman et al., 2010, Journal of Orthopaedic & Sports Physical Therapy). But it can be, and this is worth taking seriously: a compression fracture in the spine can develop with surprisingly little trauma in someone with low bone density, and may cause the upper back to round further without much pain.
Osteoporosis Canada's spine-sparing guidance for people at high fracture risk recommends limiting repetitive bending and twisting, bending fully forward or sideways, holding a bent or twisted position, and bending or twisting while holding weight — favouring hip-and-knee-hinge movement and slow, controlled motion instead (Osteoporosis Canada, Too Fit to Fracture). That source doesn't name Pilates specifically, but the principle applies directly to classic flexion- and rotation-heavy moves such as the roll-up, roll-over, teaser and spine twist, which we modify or substitute for clients with osteoporosis, osteopenia, or a history of vertebral fracture. If you have osteoporosis or are unsure about your bone density, please tell your instructor and check with your doctor before starting — we go into safe exercise choices for osteoporosis in more detail in a future post on Pilates and osteoporosis.
What can you realistically expect?
Pilates is not a quick or permanent fix for rounded shoulders. It is a strength and mobility practice that, done consistently, can support a more upright position and make holding that position feel less effortful over time. Expect gradual change with regular practice, not a one-time correction — and expect to keep practising to maintain it, the same way strength gains elsewhere in the body require ongoing training.
Safety note: This article is general information, not medical advice, and Pilates instruction is not a substitute for medical diagnosis or treatment. If you have a visibly rigid or sharply angled curve, progressive worsening, pain focused at one spinal level, numbness, tingling or weakness in your legs, or a suddenly worsening hunch in older age, see your family doctor first; a physiotherapist or spine specialist may also be appropriate. If you have osteoporosis, osteopenia, a vertebral fracture history, or have had spinal surgery, please tell us before your session and check with your doctor, so we can adapt your program accordingly.

Frequently asked questions
Is "rounded shoulders" the same thing as kyphosis?
Not exactly. Kyphosis refers to the curve of the upper spine itself, while rounded shoulders describes the position of the shoulder blades and shoulder joints, which often move together with a rounded upper back but can also occur somewhat independently.
Can rounded shoulders be improved in adults, or is it too late?
Postural rounding in adults generally responds to consistent strength and mobility work at any age, since it's driven by habit and muscle balance rather than fixed bone changes. A rigid structural curve is a different picture and should be assessed by a doctor.
Should I stretch my chest or strengthen my back for rounded shoulders?
Both, generally — this pattern typically involves a tight chest and a comparatively weak mid-back, so addressing only one side tends to be less effective than working on both together, which is how Pilates programming for this issue is usually structured.
Is my desk job the reason for my rounded shoulders?
Prolonged desk and screen postures are a common contributor for many people. We cover this in detail in our guide to Pilates for desk workers.
How long does it take to notice a difference?
This varies by person and isn't something we can promise a timeline for. The available evidence on Pilates and posture comes from supervised programs of a couple of months, done a few times weekly, with gains linked to how consistently people practise.
