If you’ve ever been told you’re hypermobile, or if you’re someone who has always been “really flexible,” this one is for you.
Hypermobility means your joints move beyond a normal range of motion. Some people find this out as kids when they can do party tricks with their fingers or elbows. Some people find out as adults when a PT or doctor mentions it. Either way, the common advice that gets handed out is almost always some version of: stretch more, do yoga, work on your flexibility.
And that advice is, pretty much across the board, wrong.
Here’s what’s actually going on. Hypermobility isn’t a flexibility issue, it’s a stability issue. Your ligaments and connective tissue are more lax than average, which means your joints don’t have the same passive support that other people’s do. That sounds like it would make you feel loose and free, and sometimes it does. But it can also mean your body is constantly working overtime to hold things together.
This is where the tightness comes in, and this part is really important.
A lot of hypermobile people feel chronically tight, especially in their hips, hamstrings, neck, and shoulders. And they assume that means they need to stretch more. But that tightness is usually not a muscle length problem. It’s your nervous system sensing that your joints aren’t properly supported and cranking up muscle tension as a protective response. Your muscles are basically doing the job your ligaments can’t.
When joints lack stability, your brain perceives that movement in those joints is unsafe and increases neuromuscular tone, that low-grade sustained muscle tension, to compensate. Stretching those muscles out doesn’t fix the instability. It just temporarily removes the protection while the underlying problem stays exactly the same.
Loosening them without addressing the underlying cause is like removing a brace before the bone has healed. You’ll feel relief for a moment, but the tension always comes back.
So what does actually help? Strength training.
The research on this is pretty consistent. Stronger muscles are better equipped to stabilize the joints and protect them against hyperextending, reducing wear and tear on the ligaments as well as the risk of injury.
Strength training also builds muscular endurance, meaning your body gets less fatigued from having to maintain stable joints. When the muscles surrounding a joint get stronger, your nervous system doesn’t have to work as hard to keep everything together. The protective tightness starts to ease up because there’s actual strength backing things up now, not just tension.
None of this means yoga or stretching is evil. But if you’re hypermobile and you’ve been chasing flexibility trying to get out of pain, and it’s not working, it’s probably not working, because flexibility isn’t the problem.
Your body isn’t broken. It’s actually really good at protecting itself. It just needs some actual support to do it.
