I have done a good deal of boxing and I must agree with the comment made about the development of a small, but ingrained repertoire. Boxers are agile, fast and can take punches a lot better than the average martial artist. They also parrie and cover up vital areas very well; have you ever tried landing a technique on a boxer and missed? if so you're not alone. The simplicity of this discipline allows for quick and powerful attacks without having to struggle with the complexities of martial arts. Their techniques are easy, but when u add unmatched speed and power to them, they are deadly. Like my Sensei in Goju would always say, you could spend your whole life practicing just the basics and never quite master them, but one who is extremely adept at a single basic punch, is a most formiddable opponent.
