I wanted to be a pro wrestler in my teens, I have no around with local wrestlers and did ring crew work from time to time when a show was local. Eventually they started giving me some training and let me tell you it takes a lot of athletic ability to make those moves look good without injuring the other person.

Just because the outcome is predetermined doesn’t mean the lead up to the outcome isn’t an athletic competition. They are competing in that ring, it’s just that they are competing for a chance at a belt and earning the belt is the equivalent of a promotion in the workplace. Champions get better pay and more opportunities.
