Because it's repetedly slamming with quite a lot of force a very vulnerable part of my body in to the ground. It HURTS. I don't luke it because it HURTS. People assuming because condition and because you don't like aren't the same thing annoy me a ton. I don't like it because it hurts. It doesn't matter if that is becuase of mu condition. Doing something over and over that hurts is not good. That is called self harm. I train in ways that feel good. And not in ways that make my body feel weaker. I swim, quite a lot and with quite a bit of skill. I'm currently working on my butterfly stroke and it's the best it's ever been. I am reallt fit. Me not running is irrelevant. I don't run, because for me running hurts.
Yep. I also do some gymnastics, and diving - which is low impact if you land right, and most of the action is in the air or upside down which stretches the muscles in another way.
You didn't offend me personally - I know you idn't mean anything bad by it. But people assuming I'm not well trained because I don't run really annoy me - and I can't say that rant to them in person.
