Bent Branderup, grandmaster of equestrianism, explains how the historical knowledge of Gustav Steinbrecht can still be utilized today for the training of horses and riders, and how these insights align with modern research on the biomechanics of horses. Together with osteopath Annika Keller, he addresses the questions of modern riding: Why is the horse's mobility so important? How can it be maintained and promoted? What benefits does it bring for rideability and health?.
