#3 Kimura
You know the Kimura lock, that oh so lovely thing that Brock Lesnar used for the first few years of his second WWE tenure.
It's a devastating submission hold and if you get caught in it there are two options - you either tap, or you get your arm broken. It really is that simple and in mixed martial arts, we all know that anything can happen at any given moment.

Getting caught in something that you weren't anticipating is what makes the sport so unpredictable, and you can bet all the money in the world that fighters would immediately start to panic if they realise that they've been subjected to a Kimura.
Just thinking about the way in which a human arm bends back whilst in this move makes us feel a little bit sick.
We move away from moves intended to submit with one intended to cause a TKO.
