A turn board (also known as turning board) is a training device commonly used in the fields of ballet, dance, ice skating, and other athletics in order to aid in the development of various dance turns. It is believed that regular use of a turning board may increase confidence and comfort while performing various moves that involve turns. In dance and gymnastics, a turn is a rotation of the body about the vertical axis. It is usually a complete rotation of the body, although quarter (90°) and half (180°) turns are possible for some types of turns.
