Stuff like this is neat but always feels a bit like a short-term bandaid.
I'd encourage folks here to check out programs like Egoscue, Alexander Technique, Gokhale method, etc for a more 'holistic' (quotes cuz its such a vague buzzword in health/wellness).
I'm halfway thru Egoscue and it's been amazing for beginning to restore my mobility from when I was a kid, but people should do their own research.
