Has anyone managed to go from clumsy and inflexible to graceful and dexterous?

[PurryCat]

And if so, how did you do it?

I'm mid-thirties, 5'11, a bit overweight (currently losing weight and getting fit though), terrible posture, really inflexible, bad sense of balance and have always been quite clumsy. Growing up, I used to be much sportier (tennis, horse riding, basketball, swimming), although to be fair, I never really excelled at any physical pursuits and none of it made me any more graceful or particularly in control of my body.

I'm a bit fed up with my ungainliness and wondering if anyone similarly hopeless has managed to improve their motor skills and posture in any significant way? Any suggestions besides yoga / pilates / dance classes? I struggle to follow dance routines and the one time I tried a yoga class I hated it and the instructor actually made fun of me so I never went back despite having paid for ten lessons upfront. 🙈

PS. Dear MN SPAG police, English is not my first language, so please bear with me!

Bryce, my hands and finger joints definitely are hypermobile, but not to the extreme extend you can see in some YouTube videos. It doesn‘t cause me pain or any other problems, though (well except for my violin teacher many moons ago despairing at how I was holding the bow because my finger joints would always flop back to bent rather than curved).
Haven‘t noticed it anywhere else on my body and I‘m pretty inflexible overall.

Hypermobility can affect spatial awareness.

Hypermobility often results in people having poor awareness of their body in space. Proprioceptive training improves spatial awareness by challenging the individual to 'feel' where their body is in space. Feedback is sent to the brain during a movement which will try to correct or fine-tune the movement.

Sometimes you wouldn't know joints are hypermobile as feels normal to you. I have a huge range of movement in my shoulders, spine and pelvis but I have tight hamstrings so I don't look.like a gymnast

Bouldering or climbing. You have to make the decision you're going to do route gracefully, rather than clambering up though. I did a lot of ballet and find it's quite a similar set of skills. The best climbers are as graceful as dancers and it really makes you aware of your balance and corners. Not one for the living room though!

Alexander Technique lessons really help with this. It teaches you how to unlearn all your bad habbits that you pick up over the years in terms of how you carry yourself.
