Hip snap or hip use is really a non-teach movement. She'll start doing it naturally and without really thinking about it once she stops flaring out the drag leg. It really is nothing more than using full adduction, driving both elbows and knees into the center of the body. With front side resistance, the front knee isn't going to move, so it is the back knee that is driven toward it. Creates a tremendous amount of core torque.
For drilling she can work on this constantly. My DD still does toe drag drills every practice as part of her warm up routine.
