Does your chest hurt if you don't do this
or what?
I tried to see if I do this but I think
too much on it and do it anyways
I know that every once in awhile I like to
take some nice big breaths to fill my
lungs when I'm sitting for too long or
something like that. I just figured it was
because I have bad posture.
Do you have a problem when you run or
anything like that?
