Last week, a client came in moving like a rusted robot. Every time she reached for something overhead—grabbing a plate from the cabinet, putting luggage in the overhead bin, existing in general—her face would scrunch up like she’d just bitten into a lemon.
“My shoulder’s been killing me for months,” she said. “I’ve stretched it. I’ve done all the band exercises from Instagram. I even tried that thing where you hang from a bar and just… dangle there like a sad piece of laundry. Nothing works.”
I had her lie on her back and try to lift her arm straight up.
It barely made it to 90 degrees before her ribs shot up like she was trying to do the world’s worst crunch, and her back arched off the table so hard I could’ve slid a pizza box under there.
“Your shoulder isn’t the problem,” I told her.
She looked at me like I’d just told her the Earth is flat.
Three weeks later, after working on breathing patterns and rib position, she pressed a dumbbell overhead pain-free for the first time in a year. No grinding. No pinching. Just… normal shoulder function.
Your shoulder pain probably isn’t a shoulder problem. It’s a “your ribs are stuck and your shoulder has nowhere to go” problem.
The Real Problem: Your Shoulder Needs Space (And Your Ribs Aren’t Giving It Any)
Here’s what nobody tells you about shoulder pain: your shoulder joint needs space to move. Like, actual physical space for the bones to glide around without smashing into each other.
When that space gets compressed because your ribs are stuck in one position, your upper back is locked up tighter than a jar of pickles, or your chest is so tight you breathe like you’re wearing a corset, your shoulder has nowhere to go.
So it grinds. It pinches. It hurts.
Think of your shoulder like a door hinge. If the door frame is crooked, the door won’t close right no matter how much you oil the hinge or how many YouTube videos you watch about “optimal hinge mechanics.”
Fix the frame, and suddenly the door works fine.
Your rib cage is the frame. Your shoulder is the door. And most people are trying to fix the door while completely ignoring that the frame is shaped like a banana.
Three Areas That Are Slowly Strangling Your Shoulder
When I assess someone’s shoulders, I’m looking at three areas that control whether the shoulder joint has room to move:
1. Front of the shoulder and chest (controls shoulder internal rotation)
When this area is tight, you can’t rotate your arm inward properly. Try to bench press with a barbell and it feels like your shoulder is being slowly pulled apart by invisible gorillas.
2. Above the shoulder blade and upper back (controls shoulder external rotation)
When this locks up, you can’t rotate your arm outward. Reaching behind your back to tuck in your shirt? Painful. Throwing a ball? Feels wrong in a way you can’t quite explain.
3. Below the shoulder blade and mid-back (controls shoulder flexion, aka lifting your arm overhead)
When this area is stiff, you can’t lift your arm overhead without your body doing some truly creative compensations. Your ribs flare out. Your back arches like a cat being startled. And now your lower back hurts too because why not, let’s just make everything hurt.
Most people are tight in all three areas. That’s why their shoulder pain doesn’t go away. They’re locked up everywhere.

The Tests You Can Do Right Now
Here’s how to figure out where you’re limited.
Test 1: Shoulder External Rotation
Lie on your back. Bend your elbow to 90 degrees and keep it tucked against your side, like you’re doing half of a very lazy bicep curl.
Now try to rotate your hand backward toward the floor, like you’re trying to show someone behind you your palm.
Can’t get your hand to touch the floor without your shoulder lifting off the ground? You’re limited in external rotation. The area above your shoulder blade is tighter than your budget after the holidays.
Test 2: Shoulder Internal Rotation
Still on your back. Bring your arm out to the side at shoulder height, elbow bent to 90 degrees. You should look like half of a goal post.
Try to rotate your hand forward toward your hip.
Can’t get your hand anywhere near the floor without your shoulder rolling forward? You’re limited in internal rotation. Your chest and the front of your shoulder are locked down harder than Fort Knox.
Test 3: Shoulder Flexion
One more. Lie on your back. Keep your ribs down and your lower back flat against the floor.
Now try to lift your arm straight overhead, like you’re reaching for something on a really high shelf while lying down.
Can’t get your arm vertical without your ribs popping up like toast or your back arching? You’re limited in flexion. The area below your shoulder blade is tight.
Most people fail at least two of these tests. Some people fail all three and then act shocked that their shoulder hurts all the time.
I failed all three when I first tested myself. Made sense why my shoulder would randomly flare up every few months for no apparent reason.

Why Stretching Doesn’t Work (And What Actually Does)
Here’s the thing: you can stretch your chest and lats until you’re blue in the face. It won’t matter if your nervous system thinks those areas need to stay tight for stability.
Your body tightens up areas it doesn’t trust. If you can’t breathe into and expand certain parts of your rib cage, your brain locks them down to protect you.
Stretching fights against that protective mechanism. Breathing works with it.
When you breathe into a tight area, really expand it, feel the ribs move, you’re telling your nervous system: “Hey, we’re good here. You can relax.”
And then it does. The tightness releases. The joint moves better.
Research on respiratory mechanics and shoulder function backs this up. Studies show that people with better thoracic expansion have better shoulder range of motion and less pain. Turns out your body works better when all the parts can actually move.
I had a client, mid-50s, desk job, neck pain so bad he was taking ibuprofen like they were Tic Tacs. Tried physical therapy, massage, one of those neck traction devices that makes you look like you’re in some sort of medieval experiment.
Nothing worked.
We tested his shoulder mobility. Terrible across the board. His upper back was so locked up it might as well have been encased in concrete.
Started doing breathing drills to expand his upper back. Three weeks later, his neck pain was gone. Not “a little better.” Gone.
His neck was just compensating for his shoulder blade not moving, and once we fixed that, his neck didn’t have to work overtime anymore.
Three Drills That Actually Help
For limited shoulder external rotation (tight upper back):
Seated Posterior Expansion Breathing
Sit on the edge of a chair. Round your upper back slightly, don’t collapse, just round a bit.
Place your elbows on something that is below chest height and have your palms facing you.
Inhale through your nose and try to push your hands backward with your ribs. Like you’re trying to inflate a balloon that’s stuck to your back.
Exhale slowly through your mouth.
Do this for 2 to 3 minutes. Yes, it’s boring. Yes, it looks weird. Do it anyway.
You should feel your upper back expand. If you don’t feel anything, you’re not actually breathing into that area. Try again.
For limited shoulder internal rotation (tight chest):
Supine Chest Opener Breathing
Lie on your back with your arms out to the sides at shoulder height and bent at 90 deg so your hands are near your head.
Inhale through your nose and try to expand the front of your rib cage and chest outward.
Exhale slowly and let your ribs settle back down.
Do this for 2 to 3 minutes.
Your chest should feel like it’s opening up, like someone’s slowly untying a knot that’s been there for years. Don’t force it. Let the breath do the work.
For limited shoulder flexion (tight mid-back and lats):
Lat Stretch with Breathing
While standing grab onto something sturdy like a doorframe. Pull on the object and lean back until you feel a stretch in your lat which is the area on your back by yor armpit.
Inhale and try to expand your ribs into the floor. Feel your lats and the area below your shoulder blades stretch.
Exhale and reach a bit further forward.
Do this for 2 to 3 minutes.
You should feel your lats and the area below your shoulder blades expand and release.
I do these drills myself when my shoulder starts acting up. Usually happens when I’ve been sitting hunched over my laptop for three days straight writing newsletters and ignoring my own advice.
Two days of breathing drills and suddenly my shoulder stops clicking every time I reach for something.

Stop Doing Exercises You Don’t Have the Range For
Here’s where people really screw up: they try to force exercises their shoulders physically cannot handle.
Can’t lift your arm overhead without your ribs flaring out and your back arching? Then don’t do overhead presses or pull-ups. You’re grinding your shoulder joint into oblivion and probably wrecking your lower back in the process.
Can’t rotate your arm inward properly? Then don’t barbell bench press to your chest. Use dumbbells with a neutral grip instead.
Don’t have the range? Don’t do the exercise. Revolutionary, I know.
Work on getting the range first. Then add the exercise back in.
I had a client who’d been forcing overhead pressing for months despite shoulder pain. “I just need to strengthen it,” he kept saying.
I told him to stop. Just completely stop pressing overhead. Work on his shoulder flexion and mid-back mobility instead.
Six weeks later, he had full overhead range of motion and zero pain. We added overhead pressing back in. He’s been pain-free ever since.
Your ego might not like backing off certain exercises, but your shoulder will send you a thank-you card.

This Isn’t About Perfect Posture
Everyone thinks the answer is to “sit up straight” and “pull your shoulders back” like some sort of 19th-century etiquette instructor is standing behind them with a ruler.
Doesn’t work.
You can’t maintain a position your body doesn’t have the mobility and control to support.
Forcing yourself into “good posture” without the underlying movement capacity just creates new problems. Now you’re tight in different places and wondering why you still feel like garbage.
The answer is to open up the areas that need space, teach your body to control those new ranges, and then let your posture naturally improve as a result.
I’ve seen people’s posture change dramatically just from breathing drills. Not because they’re trying to sit up straight, but because their rib cage can finally move the way it’s supposed to.
Your Shoulder Affects Everything
Here’s something most people don’t realize: shoulder limitations don’t just cause shoulder pain.
Neck pain? Often from your shoulder blade not moving right, so your neck compensates.
Elbow pain? Often from your shoulder not rotating properly, so your elbow takes extra stress.
Wrist pain? Same thing. If force isn’t distributed properly through your shoulder, something downstream pays the price.
Your shoulder is like your hip: when it doesn’t move well, everything else suffers.
I had a client with elbow pain. Tennis elbow, technically. Tried everything. Braces, stretches, those weird squeezy ball things.
We tested his shoulder. Terrible internal rotation. His shoulder couldn’t rotate properly, so his elbow was doing extra rotational work during every pressing movement.
Fixed his shoulder mobility. Elbow pain went away within a month.
It’s all connected. You can’t isolate one joint, ignore everything around it, and expect the pain to magically disappear.

You Don’t Have to Live with Achy Shoulders
I’ve worked with clients who’ve had shoulder pain for years. They’ve tried physical therapy, chiropractors, massage, acupuncture, cortisone shots. Everything.
And they still hurt.
Not because their shoulder is permanently damaged, but because nobody addressed the actual problem: their rib cage couldn’t move.
Once we fixed that, the pain went away. Sometimes in a few weeks. Sometimes in a few days.
It’s not magic. It’s just addressing the right thing instead of endlessly treating symptoms while ignoring the cause.
My shoulder randomly flares up every few months when I get lazy about my own mobility work. Two days of breathing drills, and it calms down. Every single time.
Because the problem isn’t my shoulder joint. It’s that I sat at my desk like a goblin for two weeks straight and my ribs stopped moving properly.
This Week
If your shoulder hurts, or if you just want to move better:
Test your shoulder range of motion. Do the three tests above. See where you’re limited. Be honest with yourself.
Pick one breathing drill based on what you found in your tests. Do it for 2 to 3 minutes daily. Yes, it’s boring. Do it anyway. Give it two weeks before you decide it doesn’t work.
Stop forcing exercises you don’t have the range for. If your shoulder hurts during an exercise, it’s telling you something. Listen.
Your shoulder can move better. Your neck can stop hurting. Your elbow and wrist can stop aching. But you have to address the root cause, not just endlessly treat symptoms.
If you’ve been dealing with shoulder pain that won’t go away, or if you tested yourself and failed all three tests spectacularly, let’s talk. Sometimes you just need someone to look at your movement, figure out where you’re stuck, and give you the specific drills that will actually help. Grab a time on my calendar here.
