Part 3: David explains that the rider can help her horse and encourage her forward to the jump, but her hand has to remain consistent and help her stay in packaged to the fence. They start work on a combination of fences. David notes that the mare loses her straightness and shape, and suggests the use of guide rails to help her keep her line, and a ground pole to help her keep shape. He suggests the rider stay soft and don't challenge the horse at verticals until she has gotten to a point where she is consistently jumping in shape. He also points out shorter sessions are better as the mare gets tired behind quickly.
