Is it good to harden your knuckles by punching them into wood and stuff?
Yea, I am not punching so hard that it would start a bleeding or break bones. I heard of a theory that when you hit something with some part of your body, it gets micro fractures in the bones and when they heal the bones are more harder. I am just wondering if this is good and should I keep hardening my knuckles. And yes, it would be good if I could continue this. It also makes me relieve some stress. EDIT: I have also noticed that my knuckles have gotten more bigger in the past few months that I've been doing this. It's kinda random, I don't do it on daily basis.
