For 99.5% of the people doing the breaks, I suggest examining the boundry conditions set up for the break. My favorite is the cement slab that is 3 feet long and supported on the outer 1/8th inch of both ends. You could set a glass of water on it and would break (like shown in that video). Admittedly, there are a few rare people out there who continuously train in breaking and toughening up the musculature around the hands and feet. Of course, if you look at them, they all look like they have advanced stages of arthritis.Ivan Seeking said:How can people break bricks and two by fours with their hands? I would expect the bone to break first, assuming that its not rigged.
The "technique" is called Dim-Mak (not Din). That "master" has all the highlights of a scammer. A good story, horrible technique and morons to do what he says.
