In the example with my walk I felt just how important is the role of spirals in my movements. It is not just our body that is 3-dimensional — the 3 dimensions are also at work in the dynamics of our movements, when the spirals of muscles, tendons and fascia are stretched and compressed. Of course, you can try to work out or stretch just one group of muscles, for example, when working out in a gym. Our everyday movements, however, are based on engaging the sequences of various muscle groups, which wrap our body and our limbs as spirals. (You may have seen anatomy drawings of muscles on the skeleton, where it’s easy to see that our muscles are not attached parallel to the bones, but in such a way that they wrap around the bones, forming spirals. Now physiologists are discovering that even this depiction is quite crude — muscles are a much more multidimensional system than we previously understood.) This topic is covered in detail in Spiraldynamik, an anatomical concept of movement and therapy in Germany.
