Part 1: Mark opens the session by explaining the importance of having the horse between the leg and hand, and making sure the horse is obedient to the leg and moving forward before trying to jump. The riders work on a small line of fences on a bend. Mark encourages them to understand that there is no bad distance on a bend as an inside or outside line can be used to take up or give more space. He draws attention to using their body position, and avoiding making motorbike turns but rather staying straight and in balance. As the riders jump down the line, Mark reminds them to use their inside opening rein and keep their balance in their heels so they are free to use their hand to encourage the horses to land on the correct lead.
