I mean, they pretty much all do to some degree. It's not healthy on your body to do eight Broadway shows a week. Or to be constantly switching between all-day and all-night shoots on a TV show. And performing a role of high emotional trauma every day for weeks or months takes its own kind of toll too.
Obviously nobody should be at risk of life or of permanent injury, that goes without saying.
But getting bruises while doing stunts, that's just what being a stuntperson is. Nobody is forced into it. And this is why there are stuntpeople in the first place -- it's not just for skills. Sometimes the regular actor could do it fine, but there's no time in the schedule for their body to recover afterwards.
