Is Your Posture Really the Problem?
You feel that tightness between your shoulder blades and the first thought is usually the same. It's probably my posture. My posture is terrible.
We've all had that thought, and we've all heard it from someone else too. Parents, teachers, coaches, that one coworker. Sit up straight or you'll end up in pain. Your posture is the problem.
Researchers have spent decades trying to find a link between posture and pain. They've measured spinal curves on x-ray, tracked people over years, and compared groups with and without pain. One of the most cited reviews looked at over 50 studies and found no meaningful connection between spinal alignment and pain. A more recent review pulled together dozens of prior studies and reached the same conclusion: no consistent evidence that a specific posture causes back pain.
Some of the findings are almost funny. Workers whose jobs involve constant awkward positions don't report more back pain than anyone else. Teenagers with more curve in their spine than "normal" aren't more likely to develop back pain as adults. Pregnant women whose lower back curve increases the most during pregnancy aren't more likely to end up in pain either.
There's even research suggesting the relationship runs backward. In one study, researchers induced back pain and watched people's posture change in response. Pain changed posture. Posture didn't cause the pain.
Good posture still matters, just not for the reason you've been told. It matters for body language, confidence, and how you show up. And having more options matters for performance. Being able to access a certain position can help you lift more, sprint faster, or move better in a specific moment.
I get asked pretty often... what's the "best" posture?
The one you're comfortable, and the one you don't maintain for too long.
Some say "the best posture is the next posture"
Variety beats any single "correct" shape.
Do you need to fix your posture to feel better? Only if a specific position is aggravating your symptoms. In that case, spend less time there, find something more comfortable, and gradually work your way back in. If you spend a lot of time in a specific position, it's probably a good idea to access other positions of the spine.
If you sit a lot and your mid back feels tight, these exercises won't "fix" your posture, but they'll give you access to positions you don't spend much time in, and they usually feel pretty good:
Open books: Lie on your side, knees bent, arms out in front. Rotate your top arm up and across, letting your gaze follow your hand. Feel the stretch through your mid back and chest.
Thoracic extension on the wall: Stand with your back against a wall, hands behind your head. Gently arch your upper back into the wall, keeping your low back neutral.
Couch stretch: Kneel with your back leg propped up against a couch or wall, shin vertical. Sink your hips forward for a stretch through the front of your hip and thigh.
Back extension: Lie face down, hands under your shoulders, and gently press your chest up while keeping your hips on the ground.
Try them a few times this week and see how your back responds.
