Can chins be toughened?

Chins can be toughened, soak them in vinegar over night and bake them for 45 mins.

 

You're not saying Savon hits harder than Lennox Lewis and Ike Ibeabuchi are you? He also had headgear in the amateurs.

Regardless of what you might think, it proves that chin resistance can infact improve. I know you like to think that chin is 99% a quality that can not be improved in any way possible, but even your most hated fighter Wilder has shown an increase in punch resistance from his earlier days.

It's time to throw your bias away and face the facts :hi:

 

then why don't u do it, let us know how it turns out. cheers.
