To do so requires a little understanding of the psychology of the horse. The horse is capable of deciding what makes it happy or unhappy. The horse can also determine and remember whom it likes and doesn't like. The most critical moment in the relationship between the horse and the rider is when the rider attempts to communicate with the horse. The language between the horse and the rider is important.
Horses communicate with each other by sight, vocalization, facial expressions, and body gestures.
It's the skillful blending of this communication combined with light, soft touches of the rider's hands and legs that allow the rider and horse to hold a conversation with each other. In a given two-way dialogue, the rider may ask the horse to perform an exercise and the horse positively responds to the request. It is important to praise the horse for his or her good exercises, and withhold praise when the results are not satisfactory. Riders should be honest with the horse, and over time it will react in kind. The rider must have consideration for the horse's attitude toward exercises, just as the horse should perceive them as something fun to do.
