When a fighter throws the 1-2-3 combination that we are taught from day one step out when you throw the jab, follow up with the right cross, and when you're weight is on the front leg rip that hook across his face and quarter turn out. Tyson did this which provided him with devastating power and speed. Also prevents the fighter from being off balance. I was shadowboxing when this struck me as I was getting off balance and throwing a sloppy slow hook.
