It’s August in Shrewsbury, which means peak season for local golf, tennis, pickleball, swimming, and outdoor projects. But with all that overhead swinging, reaching, and throwing comes one of the most common late-summer complaints we see at the studio: that deep, pinching ache in the front or side of the shoulder.
When your shoulder starts to ache after a long weekend on the court or in the yard, your instinct is usually to grab your elbow, pull your arm across your chest, and stretch it out.
When it still hurts the next day, you stretch harder.
At InMotion Personal Training, we want to let you in on a biomechanical secret: stretching a painful shoulder often makes the problem worse, not better. Here is why your shoulder is actually complaining, and how a functional movement approach fixes it for good.
The Mechanics: Mobility vs. Stability
The shoulder is the most mobile joint in the human body. Unlike the hip joint, which sits securely in a deep socket, your arm bone (humerus) sits against your shoulder blade like a golf ball sitting on a golf tee.
Because the socket is so shallow, the shoulder relies almost entirely on a small group of four muscles—the rotator cuff—and your shoulder blade (scapula) to keep that "golf ball" centered on the tee while you move.
When you feel a pinch or ache during overhead movements, it's rarely because the joint is "tight." More often, it’s because the rotator cuff muscles are fatigued or the shoulder blade isn't gliding properly. As a result, the arm bone drifts upward and pinches sensitive tendons against the top of the joint structure. Stretching an already irritated, hyper-mobile joint just creates more instability.
3 Functional Steps to Fix Shoulder Pinching
Instead of static stretching, focus on restoring scapular stability and rotator cuff endurance with these three principles:
Pack the Shoulder Blades Down and Back: Before performing any pulling, pushing, or lifting movement, think about pulling your shoulder blades into your "back coat pockets." This creates space inside the joint socket so tendons don't get pinched.
Build Rotator Cuff Endurance, Not Heavy Power: The rotator cuff's job isn't to lift 100 pounds; it's to keep the joint centered during long hours of activity. Light resistance band work (like face pulls and external rotations) done consistently trains these tiny muscles to stay active all day.
Strengthen the Upper Back (Thoracic Extension): If your upper back is rounded from sitting at a computer or driving, your shoulder blades tilt forward, jamming the shoulder joint. Opening up mid-back mobility allows your shoulders to move 100% pinch-free.
Keep Moving Pain-Free This August
Don't let a cranky shoulder bench you for the rest of the summer. By shifting your focus from aggressive stretching to smart stability and functional positioning, you can enjoy your favorite activities without hesitation.
