 Some trainers even run draw reins between the front legs and attach them to the cinch underneath the belly in order to get the horse to travel with the low and controversial "peanut roller" style headset popular in some western pleasure classes.However, horses can learn to evade draw reins by overflexing and putting their head practically on their chest, then charging ahead or, conversely, balking and refusing to move forward at all.There are many riders who use leverage devices, which also can include not only draw reins and running reins, but also the running martingale, to force the horse into position.
