Is your horse truly submissive and obedient? Is your horse truly forward and does the action of the rein go through his whole body equally on both sides. If the answer to these questions is a resounding yes, then the rein back will be easy to achieve and show artistry and engagement. It is an extremely beneficial exercise for the horse when correctly executed as it engages his core, strengthens his top-line and develops strength in the gaskin and suppleness through the hips. It also increases flexion of all joints in the hind end. All these benefits are of immeasurable importance as you develop your horse to piaffe, passage, pirouettes and expressive flying changes (all of which topics are covered in the recent issues of Horse Bits Magazine). The rein back is also used in training other English disciplines and also in Western training.
