Western style draw reins work similarly to the English style running rein, in that they encourage the horse to bring its head down and in. However, they may apply more leverage and because western riders rarely use the regular rein, they offer less relief to the horse. 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.
