Part 1: David sets up a line of perpendicular fences and has the riders jump through  on an angle with four strides between each. He stresses the importance of letting the horse hunt for the fence and set themselves up behind so they are actively looking for their next fence and responding. The riders focus on keeping the exercise even both ways while riding from fence to fence, keeping the line and turn intact. David reminds them to ride between two reins rather than switching from one to the other.
