I don't necessarily disagree with your overall message. But I do think you're undercounting the number of folks who get injured through ignorance. And I don't even necessarily mean traumatic injury. Even just enough injury or soreness to discourage them from trying things again can be problematic enough. Is kicking your ceiling really a good measure of some sort of fitness? Is it worth the risk of slipping and cracking your head? I don't know. Maybe. But it's far more risk of injury than walking around the block a few times and the vast majority of people really just need to start there.
