I tend to sometimes "get in" and start throwing punches at times when sparring, but someone told me that I tend to tense up and look down, or away from my opponent instead of straight at him. I suppose this comes from newbie mistakes of being glove shy. Does anybody know any tips on how to stop habits such as these? It looks extremely wimpy and also it just looks bad when a fighter gets in and his head is looking down or tilted to the side. What would a good boxer do? What would a good martial artist do?
