Inside/outside refers to the elbows, if you're inside his elbows you're gonna get beat up, with his fists, outside he has nothing because elbows are not allowed in boxing. No backhands in boxing either. If southpaw, circle towards your opponent's right. His back. The jab can't hurt you as much as the cross. I'd rather eat a jab than a cross. If the opponent is orthodox, circle towards his left. He has to turn, set his foot then throw the cross. All that buys you time for a counter of your own. Your movement is conditioning your opponent because he is trying to anticipate where you're going to be. Use that to your advantage.
