Bucking rolls are a type of horse training exercise that can help horses build strength and coordination. They work by having the horse move in a circle around an object, such as a barrel or cone, while simultaneously being asked to perform certain movements. By performing these exercises, horses learn how to shift their weight between their front and back legs, improve balance and agility, as well as increase suppleness in the body. Additionally, bucking rolls provide mental stimulation for the horse which helps reduce stress levels during riding sessions. In short, bucking rolls do work for training horses and should be included in any balanced conditioning program.
