It depends on what you mean by real or fake. It isn't really two guys trying to beat each other up. It is really two guys with a lot of physical ability putting on a show. It is scripted and choreographed. I used to know a professional wrestler( not famous ) he was one of the strongest guys I ever met and he was a good guy in real life but because of his physical appearance he usually played a bad guy in the ring. The managers and promoters told him before a match what kinds of things to say and whether he was going to win or lose. Usually he lost.
It is planned and scripted. they plan exactly what they are going to do and prepare for it. They hits and pins are real but they are only acting. If you ask me it looks really dramatic for two guys trying to wrestle. Lol.
