Professional Wrestling is wholly planned out stage drama. It's actors are steroid pumped athletes who are fully trained and practiced before they are allowed on the stage. Granted much of what they do is painful , but if they were truly trying to hurt each other , they would quickly run out of their product. How do I know it is just a big show, I know a former wrestling champion. He had to quit due to an unplanned injury.
They practice a prepared script for what they are going say, what they are going to do in the ring, who is going to win/loose. They take Steroids and other PED's , along with vitamins to get as large as they are. Yes they workout, and practice their craft. I have attended live events , sat in the 3rd row and it is obvious they throw punches that fall short by only a hair as opponents react as though really hit. I even watch with the sound off, they are great athletes. Houdini knew how to take any punch to the belly, so do they , trust me. Some do loose focus and get hurt or hurt another , but it is all just folded into the larger that they promote. It is a fun show, but never believe it is more than a staged show .
