How cAN i swing really fast and hard punches?

Question

i want to make my punches hurt more because im gonna fight a big boy i want to fight him without him hurting me but i want to hurt him

Answer 1

look man, dont hit him in the stomach or anything, if hes big thats NOT going to hurt him, face shots only, jab, jab, and move, just observe, people have tendencies, so he'll want to come right at you. most of the people after 4 swings they get tired, thats when you really move in. fake left and a right one to his jaw.
