Part 1: David introduces the rider and her horse, who's at preliminary level currently and in an eighteen month training plan to be brought along. He explains she is a great mover, but very weak behind and she has a competition in two weeks. They start warming up, focusing on leg yield and canter transitions aiming for softness. David notes that the mare tends to skip behind in the transition, so he encourages the rider to commit to the transition and focus on cantering from behind first. They being to work over fences.
