People say iron fists and iron legs, why are they so hard?
Because the fist (mainly fist face) and leg (mainly tibia) will increase the density of bone tissue in the contact area after long-term reasonable hitting training, thus increasing the hardness of bone. At the same time, because these parts are often hit, the painful nerve reaction will become dull, so you won't feel pain when you hit someone or something, but you can hold back, giving people the feeling that your fists and legs are hard!
