Part 4: Bruce works with the riders at the bank. When one rider lets his horse trip off the bank and scrape her tendons, he struggles to get her to go back down it. Bruce works with him to illustrate his mistake and assist him in building the mare's confidence again. The other rider struggles to keep his horse in front of the leg. Bruce supports him, reminding him not to let him turn away and to ride him through the exercise. They slow the lesson down, going back to walking down the bank on long reins, working on removing tension from the horses and building their confidence.
