Unitary movement is a requirement in all Internal Martial Arts.  Unitary has degrees, and the goal in most internal arts is to maximize this Unified movement.  Walu provides a number of unitary exercises at a faster clip than, for example, Tai Chi's normal pace.  These exercises are very helpful, especially for those who come from a type of movement that is hard, robotic or segmented.  Relaxation, structure, and moving from the dan tian or waist is mostly used with another aspect developed, referred to as Tsun Kwan or nerve launch motion.  These actions are inserted into the already unified moving body.
