- Good ridning means that you stop disturbing the horse, and that is one thing I find it important to tell everybody; get out of the way, cause you are the problem, says Arne Koets, who during his five years as a rider and curator at the Fürstliche Hofreitschule in Bückeburg truly started to master the art of riding and the High School movements. He is a very versatile trainer and a full-time professional instructor in HEMA (Historical European Martial Art). Photo: Matilde Brandt www.clanofthehorses.com
