Is there anyway to train yourself to make your bones for example your knuckes harder and stronger?
I used to do Knuckle push ups when I was younger to help deaden the nerves and be able to take more punishment in my hands...I've injured my hands before and it sucks, takes mad long to heal, but once they've healed they feel stronger.
I dont know what it is called, but there is a particular martial arts style that deals with bone thickening and strengthing, but I would imagine that it would take a long time to get to that point. There again, putting loads on bones helps them grow, but too much will still cause them to break. Good luck!
I remember reading that Ancient practicioners of martial arts would soak stones in milk then lightly stike the stones with their punching knucles. Over time this would condition the knucles to be harder and tougher.
I dont know about the stones in milk, but Im pretty sure the idea would stand for any hard surface you decided to regularly practice this technique on...a sand bag maybe.
I would think any time you subject your bones to impact they would adapt by becoming stronger. I saw a documentary a long time ago on some martial arts style practiced by monks where they would headbutt each other repeatedly to strengthen their skulls.
The only time it's bad to feel the burn is when you're peeing...
