American Grand Prix dressage rider and biomechanics trainer Suzie Peacock, helps Amy McCormick to improve her balance on the 8 year old Vaz, who is working at Advanced Medium. Starting with 'tractioning the spine', Suzie shows Amy how to stack and stretch her bones into the correct alignment. She says, "when we are tight in our back, the horse is tight in theirs". She explains how Amy can breath with a purpose, "breath in to grow taller and breath out to lengthen and deepen". Suzie explains clearly how Amy should position her seat bones for maximum effect. She says, "be a lazy rider and let your horse do more of the work!"
