Riders have three important aids that allow them to successfully achieve bending with horses. Those three aids are as follows:
Inside leg at the girth
Outside leg behind the girth
Outside rein
The inside rein alone does not aid in accomplishing bending in horses. In fact, utilization of the inside rein often contributes to the detriment of bend, as use of the inside rein will result in a lot of bend in the neck, typically, with little or no bend accomplished with the horse’s body.
