1. Joshua Fabia
Fabia is the wackiest combat sports coach of all-time. We use the word ‘coach’ loosely because his methods were bizarre and disturbing. The leader of ‘The School of Self-Awareness’ trained UFC fighter Diego Sanchez before it all went badly wrong. In one fight against Michael Pereira, Fabia told Sanchez, “Do not let him trigger you.”

Furthermore, his training methods were psychotic. Video footage emerged of Fabia punching and kicking Sanchez as he hung upside down from a beam. Later, Fabia explained that he hit Sanchez 20 times per day. Then, there were other insane practices. For example, Fabia once chased Sanchez around the ring with a knife. In the end, Sanchez cut ties with the weirdo.
