The renowned veterinarian, trainer, and author of the bestsellers "Finger in der Wunde" and "Balanceakt," Dr. Gerd Heuschmann, addresses an extremely important topic in the training of horses and riders in his new work. He demonstrates why true collection cannot exist without correct positioning and bending. The path from a horse in horizontal balance to a collected horse can only be achieved through proper bending. The anatomical and biomechanical foundations of this crucial training component will be explained in writing for the first time, incorporating anatomy and biomechanics. The riding necessity and its development have been known since the 19th century, but the "why" has not been thoroughly explained.
