Re: Boxing style
listen to your coach first of all, take some power off your combinations, that will use less energy. If your left hook is you best punch throw make it a secret and let your opponent learn about it the hard way. If your left hook leaves you open shorten it to close the opening or only use it when your opponent is back on his heels and less like to fire anything signifigant back at you. Better yet ask your coach what his solution for your left hook.
