Firstl,y I know there was a topic on this and someone posted a link to a site that told you how to get a KO punch, but what it didn't do is tell you the exact way to throw a big, fast hard hitting punch. Should a punch be thrown from the shoulder, with the arm extending as the punch is thrown, and a step towards your opponent? OR, should your arm stay rigid before you hit your opponent? Any advice would be great!
