What is the correct body position for a rider during the cutting run after the hand is dropped?

Once the cutting rider drops the rein hand to the saddle horn and the horse takes over responsibility for the cow, the rider's job becomes primarily one of staying out of the horse's way while remaining balanced enough to stay aboard through whatever athletic movements follow. This sounds passive, but maintaining a correct, balanced position through the explosive lateral movements of a working cutting horse is genuinely demanding, and a rider whose position is incorrect will interfere with the horse's movement even without intending to. The dropped rein hand should rest on the saddle horn or thigh without gripping it — using the horn for balance by gripping it tightly locks the rider's upper body and prevents it from absorbing the horse's lateral movements naturally. The free hand can rest on the thigh or balance slightly away from the body, but should not flail or grab in response to sudden movements. Riders who clutch the horn with both hands when the horse moves hard have transferred their anxiety to a physical tension that the horse can feel through the seat. The seat itself should be deep and centered, with the rider's weight distributed evenly through both seat bones and the lower back mobile enough to follow the horse's lateral movement without bracing against it. A rider who braces through the lower back during a sharp stop or lateral cut is creating resistance in the saddle that the horse has to work against at exactly the moment it needs maximum freedom of movement through its hindquarters. The legs should hang quietly against the horse's sides without gripping. Gripping with the knees or calves during the horse's athletic movements pushes the rider up out of the saddle rather than keeping them down in it, which is counterproductive. A rider who learns to breathe and stay soft through the horse's most explosive movements gives the horse the clearest possible freedom to work.
