No, that's totally helpful. I don't need to pass any sort of physical fitness test, I just don't want to be the guy panting on the stairs when you're running for the safe room and the elevators have gone out, you know? I don't really foresee a whole lot of endurance jogging in my future either way, so since I'm also bad at jogging I'll focus on strength, and sprint/interval training instead until someone professional convinces me differently!
