Lunging and training system. Consisting of a nylon hind harness connected with two elastic rubber connectors that are buckled into the snaffle rings. Supplied without lunge line. This lunging system was developed in collaboration with Michael Freund, the world-famous four-in-hand driver. The hind legs give small impulses to the horse's mouth with every step via the hind harness and therefore via the rubber connectors. The always gentle connection to the horse's mouth results in constant, gentle aids. The horse begins to chew, steps more with its hindquarters under the center of gravity, arches its back and becomes more relaxed overall. It is ideal for building and strengthening the back muscles. It is ideal for young horses for lunging, as preparation for driving horses but also for correcting older riding and driving horses. Thanks to the versatile adjustment options, it can be used for horses of different sizes with different levels of training.
