Have you ever watched "The Wrestler"? It may be "fake" in the sense that, no, they aren't really fighting, but it's certainly an amazing, powerful sport, and while they do pull their strikes, they do have to hit hard/broadly enough to make a sound. (Sometimes guys like Jericho skip faking on some moves just to make sure your suspension of disbelief is still up.) They are actually, legitimately fucked up by the end of it. A lot goes into putting on a show for the stories of pro wrestling, and it makes me feel kinda bad that wrestlers have to be abused by just atrociously shitty writers like this.
