My horse keeps turning in when longing what should I do?

A horse that turns in toward the handler during longeing — spinning to face the center of the circle rather than continuing forward on the track — is one of the most common and most easily established longeing problems, and it is common specifically because it is so easy to inadvertently train through the handler's own body language and positioning during early longeing work. The most frequent cause is handler position. A handler who drifts toward the horse's head during longeing, who squares her shoulders to face the horse directly, or who steps in front of the horse's drive line removes the forward-driving energy that keeps the horse moving on the circle and replaces it with blocking energy that asks the horse to stop and face. The horse that turns in is often simply reading those unintentional signals correctly, which means the correction begins with the handler examining and correcting her own position before attempting to correct the horse. The correct handler position for maintaining forward movement on the longe is behind the horse's drive line — positioned roughly at the horse's hip or barrel rather than at his head or shoulder — with the body angled to direct energy toward the hindquarters. From this position the longe whip can be used to maintain forward energy by pointing toward or gently swinging toward the hindquarters, and the handler's body energy is naturally driving rather than blocking. When the horse does begin to turn in, the correction is immediate forward pressure from the whip toward the hindquarters combined with a step toward the horse's hip to block the turn and redirect him forward. The goal is to interrupt the turn before it is completed and redirect the horse's energy back onto the circle, not to reprimand the horse for a behavior that the handler's own positioning may have invited. Longeing in a smaller enclosed space — a round pen if available — removes the option of turning in entirely because the fence line takes over the containment function. A horse that has established the turning-in habit strongly benefits from several sessions in the round pen where the behavior is simply not possible before returning to open longe line work with corrected handler positioning. The longe line itself can also contribute to turning in when held with too much backward tension — a taut line pulling the horse's head toward the center gives the horse a physical reason to follow that tension inward.
