Transforming the notion into the motion, it’s the process of using our biomechanical understanding of function to design comprehensive Chain Reaction® environments. One of the most powerful forms of transformation is the science of tweak, or tweakology. In this issue of the Functional Video Digest Series, Gary Gray digs deep into movement tweakology. He provides the 3D Dumbbell Matrix and strategically explains how important and critical it can be for tweakology. Throughout the DVD, Gary provides a better understanding of tweakology, discussing plane, range, position, and joint movement techniques, and explains just how powerful it can be for evaluating, rehabilitating, and training. Understanding this concept will empower you and all those you take care to enjoy function for a lifetime.
