Keeping the Center

It is important to maintaining good posture in the form of a straight axis from the top of the head through the spinal column to the coccyx. With this achieved, the arms can be "locked up" using the elbows and pectoral muscles.  Rotating the body around this axial center without leaning or bending at an angle is the key to keeping balance, and forms the basis for the various "pulling" and blocking techniques found in Gojuryu and other martial arts, such as Tai Chi, which is explained here.  The principles are the same, and can be practiced in kakie.
