What it is
Rounded shoulder posture is a forward position of the shoulders with scapular protraction and internal rotation. It often coexists with forward head posture and upper thoracic flexion. It is a modifiable habit influenced by strength, mobility, and task demands.
Improving posture is about capacity and variety rather than holding a rigid pose.
What happens when it occurs
Protracted scapulae reduce the subacromial space, biasing the cuff to work at a mechanical disadvantage. Thoracic stiffness limits overhead motion. Training restores scapular position, thoracic extension, and cuff strength.
Common causes and risk factors
- Long sitting and device use
- High pressing volumes without balancing pulls
- Thoracic stiffness and a weak posterior chain
- Pain avoidance habits after injury
Who is most affected
Office workers, students, and lifters who favour pressing exercises.
Typical symptoms
- Dull ache between the shoulder blades
- Pinching with overhead reach
- Fatigue during prolonged sitting or typing
When to seek care
If symptoms persist or disturb sleep and work.
How we diagnose
Posture and movement analysis, scapular position tests, thoracic mobility, and cuff strength. Imaging is not required.
Management
- Thoracic extension and rotation mobility
- Strength for the lower trapezius, rhomboids, and external rotators
- Technique coaching for reach, row, and press tasks
- Workstation and daily movement planning
Rehabilitation milestones
Phase 1 weeks 0 to 3: mobility sets, activation of lower trapezius and serratus.
Phase 2 weeks 3 to 8: heavy slow rows and external rotation strength.
Phase 3 weeks 8 to 16: overhead capacity, endurance circuits for posture tasks.
Phase 4 months 4 to 6: performance targets and maintenance.
Readiness to progress
- Improved scapular position at rest and during reach
- External rotation strength within 90 per cent
- Workday comfort is stable across a week
Prevention
- Balance training across the week
- Use micro breaks and varied positions
- Keep posterior chain strength high
Australia snapshot
- Common in desk roles and among students
- Seen in lifters who prioritise pressing
- Services for ergonomic review and rehabilitation are widely available
Latest insights
You do not need a perfect pose. Build capacity and vary positions throughout the day.
Strength for the back of the shoulder changes comfort and function.
