Have you ever wondered how can Karate and Kung Fu practitioners break woods and bricks by their bare hands ? … Well at least I wondered a lot as a martial artist and a doctor … how can the human hand tolerate such a big trauma and still in one piece??
Nice illustration! Just to chip in my 2 cents, there are considered 2 basic ways to condition the body, including the hands in "iron palm". One way is to do as you describe. The other way is to hit very relaxedly and not too hard for about 100 times a day for at least 3 or 4 months, each time 'bringing the qi" to the hand. In other words, there's a mental and bodily function that trains the flesh and bones. The point I'm making is simply that your illustration and comments are correct, but there is considered to be a "higher level" of conditioning than the one you're describing.
