Now the damned southpaws have manged to make the English language confusing...
Watch the very start of this fight. Toney comes out, makes a move to creat the opening for the hook and then throw it text book; watch where his weight ends up. If you watch the rest of the fight, you'll see how to throw short hard punches in combination, shifting your weight at close range. You'll learn how to slide back, turn angles and get weight behind your punches as you do so.
