LARRY TROCHA (reining and cutting trainer) just uploaded two new training videos to youtube. In this two-part video series, he shows what cues the rider needs to use to ask a horse for correct turns and spins. Special attention is given to how the rider should use his hands (look at his arm position in the spin, Tiffany!!), legs and seat to get a good response from the horse.
Here are the links to the videos:
