I took Zum to Wickenburg and on his first day of training, Buddy showed me the importance of turning Zum’s head to the right with the right rein and making Zum move his hindquarters over to the left. Then Buddy turns Zum’s head to the left with the left rein and makes Zum’s hindquarters move over to the right. Over and over. If Zum is afraid of something, Buddy makes Zum move in serpentine motions again and again. This is using flexion to bend the horse.
