As someone who is pretty flexible, I see it as almost a bit of a curse.
can make your joints unstable or “loose” - to the extent that it feels like certain things won’t stay in place (which is where strength comes in).
If you habitually have your scapulae in any given position, it starts to feel like that is neutral and so you lose the ability to tell where your shoulders really are in space.
Which means, when doing yoga and bearing weight through your hands and arms, you will tend to line your hands up under where you THINK your shoulderblades are. And that is a cause of wrist pain.
Those of us (like, pretty much all of us) who thrust our ribcages forward thinking that's how you 'stand up straight' are articulating just one joint of the many in our spines - often the joint between T11 & T12 - ALL the time.
If you think 'lifting your chest' or 'sticking your chest out' is what standing up straight is, you are misinformed. Pretty much everyone is - that's why we are pretty much ALL rib shearers.
Back in the day, I was taught to teach people to kick up into headstand. So I did. I CRINGE when I think back on that.
I JUST KNEW SO LITTLE ABOUT HOW BODIES WORK.
But then, at the time, very few people in the yoga world knew anything much about modern biomechanics. Thank goodness we are learning!
AS I’VE LEARNED MORE, I’VE BECOME INCREASINGLY WARY OF INVERSIONS. This is why.
