Grand Prix dressage rider Hannah Biggs works on rhythm, speed control, transitions and suppling with the four year old Archie. "Riding a serpentine on a youngster is a lot more difficult that you think" she says. "Every stride must be exactly the same, so it shows up any weakness". Hannah demonstrates how to apply the leg and uses transitions to get Archie to push more from behind. "The trot must swing like a metronome." In the canter, Hannah challenges Archie by reducing the size of the circle and also offers tips for improving a horse's weak side. "With young horses, it's a balancing act between pushing enough but not too much!".
