Anyone's hands and knuckles are "hard". To the contrary, a boxer's hand are quite vulnerable when punching which is why a boxer's hands are wrapped.
id say so have to people the same age on with soft knuckles that you can push down on and cave in against one with harder knuckles where there first two knuckles are bigger than the rest and have both of them practice on a punching bag youll notice the differnece.
Urination ,taking an enima ,sweating through exercise ,sitting in a sauna.
nope its on the timing and how you punch
Do people that hit hard have hard hands and knuckles and does this have anything to do with your punching power
