AKA "the human side rein effect". It annoys me to no end! People do this to force their horses to put their heads down, but like Kayty said, it does not engage the hind end. It is not an effective or productive way to ride. A lot of people have a tendency to focus on one thing, the horse's head. If you ever get confused, look at some of the professionals, Lars Peterson, Todd Flettrich, they NEVER have their hands down and wide....
