I recently enjoyed working with a small woman who was a relatively inexperienced rider with a black belt in karate. The parallels between riding skills, and her skill as a martial artist, delighted both of us. This podcast reviews the relationship between the lines of muscle and connective tissue along the front of people (the underneath of horses) and the back of the body. It adds the novel and life-changing idea of the horse’s ‘chest plate’, which I dreamed up after doing an enlightening exercise in a class with Tom Myers. This created a powerful new way to think about collection.
