Stances are the foundations or basic building blocks of Tae Kwon Do. All the kicks, blocks and strikes are launched from a stance. The stance will depend on the situation, defence, counter technique, direction of motion etc. If the stance is not correct and strong then the technique will become weak and pointless.
