Iron Fist ??? and Iron Body ?

[BulletProofMonk]

I have heard legends of men who punch holes through brick walls, break concrete bricks with their fists and are invunurable to tigers claw when attached on the lower body. Can anyone hear smash bricks with their fists and kick bricks and stuff.

How does one develop the iron fist and iron shirt ? How does one become immune to tigers claw as the chinese say ?

Anyone can do that stuff. Requires no skill so much as strength. Helps to have a high tolerance for pain too

Hard Chi Kung called Wai Jia for vest. Striking over and over for fist. Screw your hands up if done wrong. Chances you take and for what?
