Very untrue. Many martial arts can lend a hand in a fight, but I'll tell you the styles you listed aren't well rounded enough to keep you in good shape in any fight. BJJ is a decent style but far from complete. Many styles have too many restrictions, both in fighting and in movement. No one style can prepare you for everything.svang55;4320611;4320611 said:i think there are only 2 or 3 arts that will help you in a real fight. i'd do bjj, muay thai/kickboxing and boxing. all the other stuff is only for competition where there are rules and points and things like that

The styles you listed, leg attacks. Kickboxing/muay thai are good styles, but they do not have a wide variety of strong ranged kicks. Boxing only helps if you have gloves, and need to learn to take a hit to the head. None of these styles focus on pressure points, or manipulations of tendons, nerves, blood flow, or muscles. There are several places on the torso that can knock even the most toughened fighter out with a simple punch, but most styles do not learn to focus on hitting weak points, just hitting where they can.
