Shape

Humans have many joints and can use their entire body to create various shapes. In this book, the shape of the entire body created by changes in joint movement is referred to as “body shape.” When considering the dexterity of physical movements, such as those in various sports and dances, strong, fast, and beautiful movements are achieved by skillfully combining body shape, flexibility from muscle tension, and their changes over time. Generally, the number of combinations is vast, and finding the appropriate solution is extremely challenging. Even when limited to body shape, the human body has more than 200 joints, and the possible combinations of their angles are enormous.
