Okay, Please do not laugh. I remember hearing in high school by my friend that punching you knuckles against a hard surface such as a brick wall, it would harden you knucles, Is this true?
Well, if by 'harden' you mean arthritic and broken, then yes. Punching a brick wall ought to do it. :thumbsup
You all suck, he has a legitamate question. He's just got a dumb friend is all lol either that or he wants him to break his hand. You can do knuckle pushups, get a small bag of sand and strike it every morning for 5-10 minutes, even just hitting the heavybag will build the bones in your hands (it just has to be a heavy or hard packed one), another way is to put a large newspaper up to a hard surface (brick wall OMG!) and strike it, the paper will act like padding. You should start light and slowly over time hit it harder and slowly remove one sheet of paper at a time. The only ones I would ACTUALLY recommend is the knuckle pushups, heavybag and the bag of sand if your really serious about it.
well hard knuckels wont help your boxing as you would have gloves on anyways. but there is some truth to this. when bones break they heal stronger. of course unless its a major break. i was watching that fight science thing on the discovery channel and they where talking about two guys who break concrete and stuff as a martial art. and there bones would fracture and heal back harder. thus making them capable of breaking more concrete blocks.
Seeing this iza boxing forum, I strongly recommend you protect your hands. Protect them training, sparring and fighting. Protect them always. Wrap properly, glove properly. You want to strengthen, worry about wrists and forearms. Nothing wrong with using grips to strengthen them either. But don't listen to any **** about 'roughing up is toughing up your hands'... For like one set of eyes for life, you only get one set of hands for boxing. Fuk either of them up by doing anything as stupid as punching a wall, and say goodbye to knowing this sport any further from a potential fighters perspective.
