So in an effort to "improve my posture and strengthen my core" I am using a balance ball instead of a desk chair while working at the computer. I've been using it consistently for the last three days but all I'm feeling is intense pain in my upper back. It is just that I'm such a weakling and I should keep at it or something else?
