martial arts, page-3

what the worlds most effective martial art in a street fight,and why?

-> forced to be narrow, i would say jiu-jitsu.. i think an average jiu-jitsu fighter is going to beat an average fighter of most other disciplines

"why are some arts less effective?"

-> because they are too rigid and not flexible

"what ones are useless?and why?"

-> i wouldn't call many useless.. lyoto machida makes karate look pretty effective

"if you had to have someone fight for your life,who and why?"

probably anderson silva, because i wouldn't be concerned and could sit back and enjoy the fight
