The moves, the physiques and some of the slamming (and injuries) are real, however the outcomes are all staged, and a lot of the moves are rehearsed (and the wrestlers are all "charachters. ")
The professioinal wrestling is scripted with the winners and losers predetermined. The participants practice the moves before the match in front of an audience. The wrestling for high school and colleges and the Olympics is real.
The "wrestling" perform on tv today is perform by actors who wear costumes and follow a scripted plan. Usually the winner is predetermined and they just put on a show.
Ya sometimes it may be fake... But not completely it is fake. Some fighters will cheat the audience but not every fighter will cheat the audience … if we watch keenly watch the match means we can clearly identify that whether it is fake or real…
