Side reins, draw reins, and running reins are all types of training aids used in horse riding. Side reins are attached to the girth and the bit, running parallel to the horse's body, to encourage the horse to work in a consistent frame. Draw reins are attached to the girth and run through the bit rings, encouraging the horse to lower its head and flex at the poll. Running reins are similar to draw reins but are attached to the saddle and run through the bit rings, encouraging the horse to work in a round frame. These aids should be used with caution and under the guidance of a knowledgeable trainer, as they can be misused and cause harm to the horse if used incorrectly. **
