Thoracic scoliosis — a curve through the mid and upper back, where the spine carries the ribs — is the most common pattern, and it’s the one that people notice in the mirror: one shoulder blade sitting higher or sticking out, a “rib hump” that shows when you bend forward, and sometimes a feeling that one side of the chest simply doesn’t fill with air. That last point is the key to this whole guide. Because the ribs attach to the thoracic vertebrae, a thoracic curve rotates the rib cage with it, compressing the ribs on the concave side and pushing them outward on the convex side. So exercises for thoracic scoliosis lean heavily on breathing — using the breath itself to expand the collapsed side — alongside mid-back strength and de-rotation. For the wider picture, start with the hub guide to exercises for scoliosis.
Key takeaway: Exercises for thoracic scoliosis centre on breathing into the concave side of the curve to expand compressed ribs, de-rotating the rib cage, and strengthening the mid-back and shoulder blades. Rotational breathing, side-lying breathing over a towel, wall angels, band rows and swan prep form the core routine. Exercise manages a thoracic curve and can soften a rib hump in posture; it does not straighten the spine.
The best exercises for thoracic scoliosis expand the concave side and strengthen the mid-back: rotational breathing with a hand on the concave ribs, side-lying breathing over a rolled towel, mermaid stretch toward the convex side, cat-cow, wall angels and band rows for the shoulder blades, swan prep for the upper-back extensors, and bird-dog for rotational control. Avoid deep backbends, heavy overhead pressing and side-bending toward the concave side. Sophie Mercer, PMA-certified clinical Pilates instructor, designed a 10-week Scoliosis Management protocol of 36 exercises that build balanced strength and control around an asymmetric spine.
Why the rib hump matters — and what it tells you
The rib hump isn’t a separate problem; it’s the curve made visible. As the thoracic vertebrae bend sideways they also rotate, and because the ribs are attached, they rotate too: backward on the convex side (creating the prominence you see in a forward bend) and forward on the concave side (where the ribs crowd together and the chest can look flatter). The muscles between and over the ribs adapt to this — short and tight on the concave side, stretched and weak on the convex side — and the breath follows the path of least resistance into the already-open side. The hump tells you which side is convex, and it tells you where the breath needs to go: into the concave side. That’s the organising principle behind the Schroth method, and it’s the first thing I teach anyone with a thoracic curve.
The breathing exercises
Do these daily; they’re the foundation everything else builds on.
- Rotational breathing — Sit or lie down. Place one hand on the ribs of the concave side, roughly at the level of the bottom of the shoulder blade. Inhale slowly and direct the breath under the hand, feeling the ribs push it outward and backward. Exhale fully and let the trunk lengthen. 10 breaths, 2-3 times a day. Feel: the hand being moved by the ribs beneath it. Avoid: lifting the shoulders or arching the back.
- Side-lying breathing over a towel — Lie on the convex side with a small rolled towel under the waist, top arm reaching overhead. The concave side is now on top and opened. Breathe into the top ribs for 10 breaths. Feel: space opening along the top side. Avoid: holding the breath or bracing.
- Wall-supported de-rotation breath — Stand with your back to a wall, both shoulder blades touching it if you can. Inhale into the concave ribs while gently pressing the convex-side shoulder blade toward the wall. 8 breaths. Feel: the rib hump softening backward. Avoid: forcing — this is a suggestion to the rib cage, not a push.
Mid-back stretches and mobility
- Mermaid toward the convex side — Sit with legs folded to one side, one hand on the floor. Reach the other arm overhead and side-bend toward the convex side, so the concave side lengthens. 5 breaths, 3 times. Do not bend the other way. Feel: the concave-side ribs and waist opening. Avoid: collapsing into the supporting shoulder.
- Cat-cow — Round the spine on the exhale, lengthen on the inhale, paying particular attention to the stiff mid-back segments. 8-10 slow cycles. Feel: the thoracic spine moving, not just the low back. Avoid: over-arching the lumbar spine to compensate.
- Thread-the-needle (one direction) — On hands and knees, slide one arm under the body and rest the shoulder on the floor, rotating the mid-back. Favour the direction that de-rotates your curve — your clinician can confirm — and keep the other side gentle. 5 breaths. Feel: rotation through the mid-back. Avoid: forcing range.
These sit alongside the gentler options in stretching exercises for scoliosis.
Strengthening the mid-back and shoulder blades
- Wall angels — Stand against a wall, arms in a goalpost shape. Slide the arms up and down keeping forearms and wrists as close to the wall as possible. 8-10 slow reps. Feel: the muscles between the shoulder blades. Avoid: the ribs flaring forward off the wall.
- Band row (concave-side emphasis) — Row a resistance band with both arms, drawing the shoulder blades down and back while the trunk stays long. 12 reps, 2 sets, plus one set with the concave-side arm alone. Feel: the mid-back working evenly. Avoid: twisting to pull.
- Swan prep — Face down, hands under shoulders, pubic bone anchored. Lengthen forward and lift the chest a few centimetres. 6 reps, 3 breaths each. Feel: the upper-back extensors. Avoid: a big backbend.
- Bird-dog — Opposite arm and leg reach with the trunk absolutely level. Hold 3-5 seconds, 8 each side. Feel: the whole trunk resisting rotation. Avoid: the rib cage twisting as the arm reaches.
The deep-core guide covers how to make this rotational control the base of everything you do.
What not to do with thoracic scoliosis
- Deep repetitive backbends — they compress the already-rotated thoracic segments
- Heavy overhead pressing — load through a rotated rib cage distributes unevenly
- Side-bending toward the concave side — it shortens the side you’re trying to open
- Full-range symmetrical twists — reinforce rotation
- Forcing the rib hump flat — pressing on it does nothing useful; de-rotation comes from breath and muscle

How should I sleep with thoracic scoliosis?
Sleep is where a thoracic curve spends a third of its life, so it’s worth getting right. On your back with a supportive pillow is generally comfortable and neutral. On your side, a pillow between the knees keeps the pelvis level; some people find a small rolled towel under the waist on the convex side opens the concave ribs and eases morning stiffness. Avoid front-sleeping, which twists the neck and mid-back for hours. Beyond that, comfort is the best guide — there’s no single correct position, and a mattress that lets you change position easily matters more than any rule.
Red flags: breathlessness at rest or on mild exertion, chest pain, new numbness or weakness in the arms or legs, changes in bladder or bowel control, or a curve that appears to be changing — see a doctor promptly. Adolescents with a thoracic curve should be monitored by a specialist while growing.
How the Scoliosis Management protocol helps
Sophie’s 10-Week Scoliosis Management Program builds every one of the 36 exercises on the breathing principle described here — expanding the concave side first, then adding de-rotation, mid-back strength and postural control on top — with notes on which side to bias so the work matches your curve. Because thoracic scoliosis so often comes with rounded shoulders and neck tension, it pairs well with the 6-Week Posture Correction Program; and if you want to see the full Pilates repertoire adapted for a curve, Pilates exercises for scoliosis walks through it.
