Alot of MMA fighters are based in 2 or 3 certain forms or mixes of them. A stand-up fighter is a mix of boxing and kickboxing. Most of the fighters are also skilled in wrestling (Not the WWE kind of course lol)
I've seen fighters skilled Karate, Judo, Greco-Roman wrestling, Muay Thai, Kickboxing, boxing, Shoot wrestling, Brazilian Jiu-Jitsu, full contact karate. The list goes on and on. Each fighter is different and has different styles.
When there's a match, most fighters will train to up there skills on what the other fighter has. Rampage above is a "Freestyle Wrestling/Brawler". The "conditioning" they go through is also insane.
Chucks fighting style is kickboxing but my guess is he trains in all sorts of different styles (He's going to need it to re capture that belt lol)
