The Free Rein Equestrian Lunge Roller is a 2 piece anti gall equiprene double point roller which is designed to be used with the training system. When used with the training system, the Aid assists in encouraging the back muscles to work set in the low position on the roller, which developes the muscles at the base of the neck, and also in the high position, which is similar to that of a ridden horse. The system when used correctly can also be an excellent tool for helping horses find their own balance. Whilst cantering, the training aid encourages the horse to take the weight off the forehand and bring the hindquarters underneath the horse. This roller does not include the training system which can be purchased separately or as a complete system.
