Speed and mass combine to apply the necessary force. It also requires the mind to understand that pain does not necessarily mean damage.
And don't try it unless you have been trained!
A Pork Chop
You need the martial art
Mansome - 2012 Karate Chop Wood 2-14 was released on: USA: 21 March 2013
Depends on the position of the board, and the technique used (Knife hand strike, or upset knife hand strike). Their really is no way to explain this. I suggest not trying to do this. Take Karate lessons because if you do it wrong you can really hurt yourself. Some pointers for those who take Karate are: 1. The harder you hit the board, the faster it'll break, and the less it will hurt. While you may think that the slower you hit the board the less it will hurt, it is the opposite. I mean think about it? Would you rather hit the board once, or ten times? 2. Do not aim for the board, aim through it. If you aim at the board that's where you will stop, meaning that you will not be at the height of your power when you hit the board. This will make it significantly harder and it will also hurt a lot more. The best way to simplify this is, when breaking the board aim for those holding it. 3. Depending on the technique were you step and the distance which you step matters greatly! Make sure you are stepping with the correct foot, in the correct direction, and stepping with the correct distance. 4. Targeting is extremely important. The more you hit its center the easier it will be. Also if you are breaking a re-breakable board targeting is everything. 5. For many karate techniques rotation is very important. You need to rotate your hand at the last second rather then at the beginning of your technique. You need to rotate that hand for a good knife hand chop*. 6. When Chopping the board the hand that is not executing the technique is not lying around doing nothing. Based on the technique that hand is moving to a certain position and rotating a certain way. Once again please do not just decide to do this. Please be taking karate lessons and be taught by a professional. You could very easily break your hand if you execute the technique incorrectly. * Knife Hand Chop is the correct term for this technique, not Karate Chop.8.when you are close to the middle go faster
What kind of pig knows karate? A pork chop!
result well be, the wood well break and the guy will fell nothing
You don't need to have a karate expert to break a block of wood, but it is definitely better to have someone who is experienced to do it. Would you rather have an experienced karateka break a board, or have an unexperienced karateka break it and end up breaking their self (such as hand, or foot) because they don't know how to properly break it?
It does not serve a purpose in the learning of karate. Anyone can learn to break a board with a few minutes of training and explanation. And as Bruce Lee said, "Boards don't fight back."
