Abstract:
1. Exercise apparatus comprising a balance board in combination with a ball; the balance board being shaped to define a generally longitudinal direction and a direction generally transverse to the longitudinal direction; the board having a top side that extends continuously over the longitudinal and transverse extent of the board, the whole surface of which top side is available for a user to balance upon, and an under side; the board being formed from a first top portion defining said top side and having a substantially flat region on its under side and a second lower portion defining a wall projecting from the substantially flat region and having an inner surface defining a region at least substantially bounded by said inner surface and consisting of at least a portion of said substantially flat region, the distance across the bounded region in the longitudinal direction of the board being greater than in the transverse direction, and the ball having a diameter less than the distance across the bounded region in the transverse direction; the ball being entirely separate from the board, and the bounded region being arranged to be freely mounted on top of the ball; the board being enabled to move relative to the ball, when the bounded region is balanced on the ball and a user balances on the top side, with at least a degree of spherical rotational freedom and also a degree of translational freedom in directions other than the vertical, and with the inner surface of the wall defining both a maximum extent for movement of the board relative to the ball and a restraint against the ball rolling out from under the bounded portion.
