The pivot on the hindquarters (or spin) is commonly seen in reining, and asks the horse to ground the inside hind leg and pivot forelegs around that point. The turn on the center asks the horse to turn around an imaginary pivot point located at the center of his barrel. The horse bends in the direction of the turn, moving his forehand in the direction of the turn and his hind end in the opposite direction. This allows the horse to turn in a very confined area. Neither movement is practiced today in dressage (although the turn on the center used to be a training movement in the 18th century).
