You can definitely train to improve your chin. Neck harnesses and wrestling bridges will strengthen the neck and jaw quite dramatically to prevent the rotational impact on taking a shot. Not saying it's possible by training alone to ever become a guy like Chuvalo, LaMotta, Pryor or Chavez, but it is certainly possible to train to hold a better punch than if you did nothing.
Yeah we did a lot of work on the neck and I noticed the difference. I reckon a stronger neck would lesson the chances of getting banjoed at least
An accurate punch thrown properly from the foot and followed through properly to the temple or point of the chin will knock you out, regardless of neck strength, due to the pressure point and nerve endings. In fact, a stronger, denser neck will only actually strengthen a blow itself if under the tip of the chin or to the side of the temple! This is because your head won't jerk back or jar sideways as much which would've taken some impact away had it done so! However, a stronger, thicker neck will certainly help with absorbing hooks to the lower jaw. By hooking your opponents jaw either side of chin you will rattle his or her head sideways causing their brain to smash against their skull, causing trauma. A strongly developed, tougher neck will prevent as much whiplash effect at impact to the jaw edges, meaning a less violent brain rattle inside the skull.
Billy is right, the best chin is the one that doesn't get hit, improving your defence effectively improves your chin.
Glass can be toughened. A lot of it comes down to mental strength, and wanting to come back from a big shot.
I was always getting dropped in boxing but always straight back up with clear head. I always put it down to a operation I had on my neck as a kid. My neck is scarred and wasted on one side. Used to do lots and of neck exercises didn't seem help. If I got hit on the tip of my jaw I'm over lol
Surely a bull neck has more chance of taking a punch than a skinny Ostrich neck. Anyone will go down if hit in the right place though - every human body has weak spots.
Its one of lifes natural things youve either got it or youve not much the same as natural punch power to bang guys out . Froch is a great example of both
