I visited my wife at work today about mid day and she was lunging one of the many horses she has in for training. I don't know squat about horses but I can back up what wolfy said. In watching my wife work she walks in a small to medium circle herself to avoid "sitting and spinning". I've not seen the full process but she uses voice commands and has a whip in one hand ...not that I've ever seen her use it. The little monster as she called it that I saw her working had come a long way I guess. Started out a real freak and had to be on chains to start but none of that is needed anymore. Again I have no about horses myself but my wife went to college for equine management or something like that and has been training them for years...she knows her ...horse poo LOL
