I learned about the connection between the eyes/vision and movement of the body in an online course run by my friend and "Wisdom Coach" Cheryl Townsley, where a tutorial showed how, looking up or down with the eyes (not via movement of the head) creates an immediate increase in the range of specific arm/shoulder motions. I could quickly check this was indeed true for myself. Indeed, the connection between eye and body movement is so important that professional athletes are being trained in these types of techniques, and are given specific eye exercises to improve sports performance!
