Scapular Retraction: Should You Really 'Pull Your Shoulders Back'?

The scapula, or shoulder blade, is a flat triangle of bone on your upper back. It is not fixed in place. It slides and tilts as your arm moves, which is why the muscles around it matter so much.

Scapular retraction is the movement of drawing the shoulder blades toward the spine. Muscles in the middle of the upper back, including the middle trapezius and rhomboids, do most of the work. Teachers, coaches and desk guides often use the cue "pull your shoulders back." It sounds simple, and it can feel good for a moment. The question is whether holding it, or training it, changes pain over time.

The research on posture and shoulder pain is mixed. The points below are the ones we can stand behind.

• An umbrella review of 41 systematic reviews found no consensus that spinal posture causes low back pain [R25]. The same caution applies when people talk about posture and shoulders.
• Forward head posture is associated with neck pain. Exercise-based programs are the main treatment that has been studied for it [R27].
• Therapeutic exercise can change the forward-head angle. Whether that change reduces pain is still unsettled [R26].
• Scapular stabilization exercise improved pain and function in people with rotator-cuff-related shoulder pain [R03].
• In adults 60 and older, body composition, strength, mobility and posture are each associated with shoulder pain and disability. The evidence on forward head posture in older adults is limited and indirect [R28].

In short, strength and control are useful targets, and a posture cue is a weaker idea than it sounds.

1. Sit tall without stiffening. Rest your feet flat and let your arms hang loose. A relaxed upright position is easier to hold than a rigid one.
2. Try a gentle squeeze, seated. Draw your shoulder blades slightly toward your back pockets, then let them rest. Do five slow repeats. Stop if you feel pain.
3. Use a chair or wall for a standing version. Lean lightly against a wall with your back and shoulders, then move your arms in a slow, comfortable reach.
4. Build strength in short sessions. A few minutes of controlled pulling movement, a few times a week, is a sensible start. Light effort and good control matter more than force.
5. Change position often. Your body is built to move. Shift in your chair, stand up, and reset your shoulders when you notice you have been holding one shape for a long time.
6. Look for pain-free range. If a cue makes you tense, let it go. Relaxed movement is the goal.
