They are born. Many confuse unleashing the puncher that already was genetically there with making someone a better puncher that never had it there. Pavlik didn't figure out he had it until late in his amateur career when he just figured out how to get it off with correct distance and leverage.
My son busted my nose when he was 2 and half while I was teaching him to throw. He punches way harder than kids that are physically stronger and much larger than him. He is 7 flattening 10 year olds. I try to teach his bigger friends the same thing and they aren't even close. He was just made this way. I can punch...my little bro can't...at all. Bobby Pac/ Manny Pac.....good example.
It's the same with any athletic ability, people with natural potential will always excel unless they are exceptionally lazy and mentally incapable of comprehending and implementing techniques that have been taught to them. Only in such cases can a person with less genetic potential (but with exceptional determination and work ethic) compete or surpass in such a comparison.
The vast majority of punchers are born with it. Yes technique can be taught to punch harder but genetics don't lie. Body type, physical dimensions, bone structure etc etc.
born but i do wonder how someone like martinez all of sudden started stopping people in fights when he was never known as a puncher. there's also two types of power, the thudding kind and the stinging kind. i remember mosley said vargas' power was thudding but dlh's power was stinging.
You're either heavy-handed from day one, or you ain't. Technique 'n combos can be learned, not hand speed or punching power. The sooner boxers accept what they can do well, the better off they'll be.
If you believe that, S, have a bridge I'd like to sell you. Best a boxer can hope for after drilling 'n drilling is to look better throwing punches.
We differ in opinion here John. I wouldn't claim that a trainer can bring on a huge improvement in punching power and speed, but tweaking them to optimum levels is possible. Tricks such as ensuring the fighter turns their hands over, and using their body for leverage ensures harder punching. Helping a fighter become more comftorble throwing punches increases fluidity which has a direct effect on speed. That being said, I'd never argue that you can turn a Mayweather into a Hearns.
