Imagine this all to familiar scenario, you grab the bar, start pulling, and feel that usual pinch in your shoulder. Maybe it happens at the bottom when you're hanging or maybe it shows up as you get your chin over the bar. Or maybe your first few reps hurt, but your shoulder starts getting better as the set goes on.

At this point you have learned how to stretch it, warm up a little longer, and take a few days off after a pullup day. But when pull-ups show up in your workout again, so does the pain.

What’s getting missed here, what can you actually do about it?

What people get confused is Pull-ups demand more than just strength to get yourself over a bar. They require overhead mobility, strength throughout the pulling motion, and coordination between your shoulder, shoulder blade, and arm. Limitations in these areas can contribute to symptoms, although the pain alone doesn’t tell us what needs attention.

Your shoulder needs access to the positions you’re asking it to use.

At the bottom of a pull-up, your arms are overhead while supporting your body weight. That’s a much bigger demand than simply reaching overhead into a kitchen cabinet.

Getting into that position involves movement at both the shoulder joint and shoulder blade. If your overhead motion is limited or uncomfortable, you may adjust by arching your back, changing your grip, or avoiding part of the hang. Those adjustments aren’t automatically harmful in themselves, but they give us something to dig deeper into.

Research shows that different pull-up grips change how the shoulder and shoulder blade move.  Whether you have a pronated, neutral, or supinated grip. That helps explain why one variation may feel different from another. Each grip will have slightly different demands on the muscles it recruits and the positions it puts your shoulder into.

The useful question here is whether you have enough comfortable and usable overhead motion for your training. Just forcing a deeper hang position isn’t automatically the answer to improve the mobility.  Sometimes you need more strength and coordination in motion you already have.

Your lats provide pulling power, but they need support.

Your latissimus dorsi (the large muscles along the sides of your back) help pull your upper arms down and toward your body. During a pull-up, they work with muscles around your shoulder and elbow to move your body toward the bar.

You also need the muscles that support and guide shoulder motion. The rotator cuff helps control the upper arm at the shoulder joint, while muscles such as the serratus anterior and trapezius help position and move the shoulder blade. Their coordinated activity creates a foundation for arm movement.

Being able to grind out a pull-up tells us you can complete the task. It doesn’t tell us how much effort it took to get there or if you can do another 5 reps, and another 3 sets after that with good coordination.

Stability means controlling the movement- not holding everything in place.

Your shoulder blade is supposed to move during a pull-up. Constantly squeezing it “down and back” isn’t the goal throughout every part of the repetition.

As you pull up and lower down, your shoulder, shoulder blade, and elbow need to work together. The muscles involved have to produce the force needed, respond to your changing positions, and control your body weight.

When that coordination is difficult, the way you distribute load can change. That may contribute to irritation in a shoulder that’s already sensitive. But a wonky movement mean any damage to the muscles, and the changes in shoulder blade motion can also occur in response to pain, rather than being the cause of it. That’s why an assessment matters more than labeling every difference from a normal movement “bad mechanics.”

Think about lowering yourself slowly from the bar. Having enough strength to reach the top and having enough control to manage the descent are related abilities, but they aren’t identical.

Getting back to comfortable pull-ups takes practice at the right level.

A useful rehab plan looks at what you’re missing and gives you a manageable way to build it.

That might mean working on overhead motion, strengthening your lats and rotator cuff, or practicing assisted pulling so your shoulder blade and arm can move together under a tolerable load. 

Your training volume matters too. Even strong, coordinated shoulders can struggle when the training demands increase faster than what your body is prepared for.

Temporarily reducing repetitions, adding assistance to the move, or adjusting your grip or range may help you keep training without pain while rebuilding tolerance. The right adjustment should make the exercise more manageable without producing an escalating flareup afterward.

At Competitive Edge Physical Therapy and Performance, we assess your mobility, strength, control, and training demands together. If shoulder pain keeps changing your workouts, it might be time you figured out what the true cause of your shoulder issues are!
