WWE wrestling question

[Ill Will]

I'm not sure what your connotation of "fake" is here. In essence, it is all for show. Wrestlers are not actually trying to hurt each other or gain an advantage in a match. It should be obvious that some moves may actually cause pain and/or physical discomfort for wrestlers, but that's all part of the show. "holds and throws" are made to look like they hurt, or else we wouldn't be watching.

I meant like which ones actually hurt and which ones don't. I mean, are all the moves done supposed to hurt or are they done in a manner to not hurt as much as possible?

Wrestlers are not actually trying to hurt each other

Not sure how much clearer I can make the answer. Getting hurt is part of being a pro wrestler, but it's not an objective. Just like tackling someone in football. It can lead to getting hurt, but hurting someone is not the intention (unless you're an asshole). Injuries are just part of the game.

The chest smack, for instance, does hurt. There's no denying that. It stings, it makes a loud noise, it leaves markings, etc. Fortunately, those are the things that make for a good display. You can hear the loud clapping sound. You can see the red marks on a wrestlers chest. You can see the genuine anguish in their reaction after getting smacked. The audience reacts by saying "WOOOO!!!". That is the magic of pro wrestling. The whole point of training to become a wrestler is so that you don't hurt yourself or anyone else.
