Whenever I exercise, it brings out any anger I might be feeling. And I don't mean that in a good way, like that the anger gets channelled into the exercises and then burned out. I mean that the act of exercises takes any latent anger I might be feeling and draws it to the surface, so I find myself yelling at people who have wronged me in the past, and occasionally at the exercise people on the screen when they're giving me bad instructions.
I don't like this. I don't like the person it makes me. I never get angry at non-immediate things, except while I'm exercising. I'm a much better person when I'm sedentary. It would be enough to make me stop exercising forever, were it not for the need to keep my blood pressure low enough to stay on the pill and the circumference of my body small enough to not drift into plus-size clothing.
