Can Katas help you in anyway? The one I can think of is that it can improve your co-ordination and strength...but is it true? Last week our sensei brought a nine year old white belt to our brown belt class, and he told us to watch the white belt perform a kata (heian shodan). We were amazed on how much the boy understood about the kata and the strength he used. The reason why sensei asked him to come is that we (brown belts) can throw in occasionally our potential strength in our katas, but only for a short period of time, whereas the kid who is much younger than us did it with speed and power....and he was NINE!! tell me what you think yuen.
