my dojo any good?

board breaking is okay but you can take the same concept of it. Main concept is focusing behind or through the target not stop at it but to pentetrate the target so it will break.

same concepts can be practiced on bag or focus mits. Idea is penetration. there are other concepts you can gain out of board breaking but main idea is penetration and focus of the mind.

that concept applys to self defense becuase say for example you do a jap and a straight right. or Karate reverse punch or what ever you call your punch. to penetrate through not stop at your attened target and not causing as much damage as you would if you penetrated more.
