Lisa Wilcox demonstrates the aids she uses with a horse with a strong underneck. She starts with her seat, showing how she wants her hip flexors loose. She also discusses correct stirrup length that will help take pressure off the horse's back. She shows how she maintains her position and asks him to come through even when he's resisting. She explains how she uses her leg aid to get him to accept it and engage while keeping the outside rein low and secure and a lighter inside rein.
