As you may know, there is a martial arts style known as Ultimate fighting or "mixed martial arts" where the rules are very lax in terms of what is allowed, however the goal is simple: Score the most points, or knock out the opponent. Many consider this to be the true test of a martial art, because its basically anything goes. While there is some Karate used, most Ultimate fighters say they rely mainly on brazilian Ju-jitsu, kick boxing, and wrestling. There is often debate about how well a person would do "on the street" equiped with training in a specific martial art. Well anyone who knows this sport would probably agree that these guys (ultimate figthers) would do very well in that area. Im new to the martial arts world and I was wondering what you people think that says about other martial arts, that when it comes down to it, when the objective is to take down the opponent at all costs, they choose brazilian ju-jitsu.
