What makes kenpo a martial art and how effective is it? i only ask this question because me and my brother had an argument if it is or isn't a MA. i think it is a martial art but i couldn't back it up since i don't practice kenpo. so can someone justify me please? and by the way he was saying that kenpo was just street fighting and that it is nothing compared to kung fu. try not to be to harsh on him. lol!
