I run but hate it, every step kills me. I don't enjoy it, don't get a 'runners high'
You know when you're driving and you see a woman lumbering along and you feel sorry for her because she looks awkward, that's me!
I've been fit all my life (gym goer and martial arts) but have never mastered running, I read that some people (5%) lack a gene that sends enough oxygen to their muscles, I believe I'm one of them.
