When I was a child, I was clumsy, knock kneed, awkward, overweight...
My mother enrolled me in ballet classes, which I continued with for the next seven years. I developed excellent posture, my legs straightened out. I 'got in touch' with my body...
I could, when I focused on it, even be graceful. I developed the ability to move rhythmically. I never became a 'dancer'...but I learned a lot and it was fun. I still like to dance (alone, in private)
so, yeah, any sustained, professional, focused, effort to learn physical control is good.
Tai chi, pilates, ballet, yoga or any NON-competitive martial art are all good for improving one's physical state.
A good physical therapist will know the right way to steer you for long term development...
