A series of Arm Circle videos called Moving in Three Dimensions to introduce the planes of movement and the idea that space, rather than isolated muscle work, is the motivation for fitness design. This idea is at the heart of 3-D Workout and its functionality because when you move well in all the planes, you use all the functions of your joints. The videos are designed as teaching tools so you can practice with me in real time. Helping you learn to exercise in the space around your body.
