Hey everybody.. I'm 17 years old and spend frequent hours sitting in a chair, be it at school or at home on the computer. I also have a joint condition called Ehlers Danlos Syndrome, I don't have a serious case of it but all my joints are hyperflexible. I've come to the realization recently that my posture is terrible, and my friend says that I have rotated cuffs on my shoulders or something, I think hes right because my shoulders slant forward now from a lot of bad posture I assume. I've been trying to sit up strait in my chair more but I'm finding it sometimes painful and very uncomfotable, and my neck has been sore recently. Can anybody give me some links to guides for proper posture and any possible tips?
Thanks a bunch.
