Part 2: David incorporates the exercise into a course. The riders struggle with the mental aspect of the line, and staying sharp enough to make the turns and land each fence already riding for the next. David explains that they need to land and guide the horse onto the line and into frame using two reins, rather than pulling them with one rein. The riders discover the importance of riding the turn with the shoulders, rather than the head which then makes it difficult for the horse to complete the turn and jump. David reminds them they must be slow in their mind and thinking the exercise through, while riding aggressively.
