The document outlines a 4-part functional breakdown for biomechanics of flow that includes gross motor control, fine motor control, head and eyes, arms and hands, torso, and footwork. It then provides more details on the basic motions for head and eyes, arms and hands, torso, and footwork, including examples like eyes following the predominantly moving hand, push/pull/toss/loop/wave arm motions, torso twists from 45 to 90 degrees, and footwork including squat, lunge, step, and sway. It concludes with mentioning cueing using biomechanics and combination #4, and two ways to play using only mechanical cueing or no mechanical cueing.
