Stance and posture

In the most basic interpretation of an entry-level kata, the aggressor is allowed to grab a wrist, sleeve or lapel, and then you go through the prearranged movements step by step. In more advanced work, if one observes a higher-ranking exponent of the style, just before the aggressor makes contact, the defender moves to a different position in reaction to the upcoming grab. By the time the grab is made, the defender is already well into his movement to take advantage of the attacker’s momentum seamlessly, and then taking charge of the distance and “flow” of the encounter.
