A balance device includes an elongated board of generally rectangular shape. The board is a molded construction of glass fibers and plastic. An elongated, longitudinally and downwardly extending track molded integrally with the central part of the bottom of the board fits in an annular groove around a roller on which the board is supported to pivot about a horizontal axis. A removable stop on the board permits the device to be adjusted to restrict the relative movement between the board and a roller to facilitate learning how to balance the board on the roller. In an alternate embodiment, the board includes a timing mechanism and display mounted on the board for tracking and displaying the elapsed time the user remains balanced on the board.
