Thoracic Extension Exercises: Reversing the Slump Gently

Your spine has three sections. The neck sits at the top. The mid-back, called the thoracic spine, sits in the middle. The low back sits at the bottom. The mid-back is built to bend forward a little and to lean back, which is called extension.

Long stretches of sitting, reading or looking at a phone can keep the mid-back rounded. Many people feel that as tightness across the shoulders or a sense of reaching uphill. When the mid-back stays rounded, the shoulder blades (scapulae) can also sit forward and down.

A rounded posture is common. It is not a moral failing, and it does not need to be perfect. Posture is one piece of the picture. Only a clinician can tell you what is driving your own pain.

• Posture and shoulder pain often show up together, but the research does not show which one causes the other. A recent review found that strength, mobility, body composition and posture are each linked to shoulder pain and disability in adults over 60 [R28].
• Forward head posture is associated with neck pain, and exercise programs are the main treatment studied so far [R27]. The word to hold onto is "associated."
• Exercise can change the forward-head angle. Whether that change also changes pain is still unsettled [R26].
• A 2025 review of exercise types for rotator-cuff-related pain found that mobilization and stretching improved pain and function over about two months [R03].

Move slowly. Stop if you feel sharp pain, numbness or tingling. All of these moves can be done seated in a sturdy chair with a back.

1. Seated chest lift. Sit tall with your feet flat. Rest your hands lightly on your thighs. Gently lift your breastbone and let your upper back follow. Hold for one easy breath, then return. Repeat a few times.
2. Chair-back arch. Sit at the front of a chair with a back, and hold the chair arms. Lean back only a small amount so the chair supports your mid-back. Stop well before any pinch or pull.
3. Shoulder-blade slide. Sit tall. Draw your shoulder blades down and back, as if sliding them into your back pockets. Breathe out as you let them soften.
4. Stand and reach. If you can stand safely, lift both arms overhead and lean back very slightly from your mid-back. Return slowly. Stop if your low back pinches.
5. Breathe through each move. Let the breath guide the motion. Keep breathing easily rather than holding your breath as you lift or lean.

If you have osteoporosis, a recent fracture, or a flare of inflammatory arthritis, ask a clinician before any extension move. You may need changes.

Short, regular sessions are a practical start for most people. The research does not give one best schedule.
