Part 5: The riders tackle a course with lead changes, bending and some challenging lines. The horse Greg moved to a softer bit performs much better and is nicer in the riders hands without being disrespectful. Greg discusses body control with all of the riders, and working on maintaining particular upper body position to help the horses keep straight down the lines and have cleaner jumps. He works with one rider to keep her horse motivated as he tends to get behind the leg at quieter distances, and with another to bring her horse back to her using the collected canter from earlier in the session.
