Based on principles of pressure and release, the Pessoa Lungeing System helps to place the horse in a better position to assist muscle build-up, and increases use of the horse's back muscles. It can assist maintenance of muscle tone in fit horses, while less experienced horses can be guided into the correct shape. The Pessoa Lungeing System can be used in four different positions, depending on the horse's level of training and fitness. Invented by International show jumping rider, Nelson Pessoa, this system is designed to encourage balance and a gradual build-up of topline. It consists of an easy-to-put-together array of ropes, clips and pulleys, as well as a breeching strap that passes behind the horse's hindquarters and is used in conjunction with a training surcingle while the horse is being lunged.
