"Let me give you a bit of warning: just because you get very good at your training it should not go to your head that you are an expert. Remember, actual sparring is the ultimate, and the training is, only a means toward this. Besides running, one should also do exercises for the stomach - sit-ups, leg raises, etc. Too often one of those big-belly masters will tell you that his internal power has sunk to his stomach; he's not kidding, it is sunk and gone! To put it bluntly, he is nothing but fat and ugly."
