A horse must be extremely muscular and supple to be able to do this exercise. The horse must also have good coordination and have a powerful, supple hindquarter.
The exercise can be taught in two ways:
1. By collecting and straightening out the horse in canter.
2. By making a series of levades.
The exercise can first be trained in hand and later under the rider. When the horse responds by accident the first time, the exercise should be stopped for that day ad the horse should be rewarded thoroughly. It takes a long time (several years) until the horse can perform a fluent Terre à Terre as a two-boated canter.
