>>13324247Most UFC champions come from grappling background, wrestling, jiu jitsu, judo, in that order. Also Fedor was a sambo champion. Then Muy Thai/kickboxing. That said, UFC ruleset HEAVILY favours grappling and jiu jitsu in particular because you cannot kick a downed opponent. This literally creates scenarios like the one the Simpsons parodies where it's just someone laying down and saying, "Now fall upon me so I may dismantle you!"
In general, kickboxing, judo, and wrestling are the best combo for defending yourself. This allows you to keep people away from you and take them down to disengage. Normally in real life if one idiot wants to hurt you he has friends that are going to back him up if you get him on the ground and start cranking his arm behind his back. Being able to keep someone at length with leg kicks while avoiding their strikes, toss them to the floor, and disengage is the best for both defending yourself and also not winding up in prison because you punched them and they fell and hit their heads is the best solution.
You should also carry pocket sand.
