Iron Palm training hardens the bones and toughens the skin so they become weapons that are impervious to breaking.
The style of brick breaking in the video is taught by Master Wang. This method of brick breaking is more about how explosive your strikes can be rather than generating force. If your strikes are not explosive enough, the brick will simply catapult off the ledge. It requires more skill and concentration.
This is different than other types of brick breaking, some where the brick is held by hand or even lifted up so that it becomes easier to break.
So, the way to train to break a brick is as follows...
- Single Minded Focus: To break a brick, it requires single minded focus. All your concentration has to come through the brick. Normally a beginner may simply look at the surface of what they are hitting, but this doesn't release as much power because you are mentally stopping at the surface and not following through. Focus your mind several inches past the object, in this case, the brick and your energy will go through it.
- Coordinate the body: If you observe in the video, he drops his torso as he's striking, this gets more of his physical weight behind the strike and creates significantly more power. If you only swing your arm down, you are losing probably 70% of your strength. Your powerhouse is stored in your core.
- Relax: Before striking, your arm should be relaxed and you only tighten up right before impact. If you tighten up like an angry brawler, although it may feel powerful, it actually slows the strike down because your antagonistic muscles are creating resistance. So, relax on the swing down and then right before contact tighten up to protect your hand and solidify it so it generates a greater blow.
- Breath and Yelling: Breath and yelling also help generate more power. Yelling increases the adrenaline in your body and also produces a higher heart rate to increase blood flow. Using breathing techniques or yelling also activate the muscles in your back and abdomen (dan tian).
