A balance board has a top side and an under side. The under side is arranged to be mounted on top of a ball with a user balancing on the top side. The board is shaped to define a generally longitudinal direction and a direction generally transverse to the longitudinal direction. The board is formed from a first top portion defining the topside and having a substantially flat region on its under side and a second lower portion joined to the first top portion and defining a wall at least substantially bounding a portion of the flat region. The distance across the bounded portion in the longitudinal direction of the board is greater than in the transverse direction. With the bounded portion balanced on a ball with a diameter less than the distance across the bounded portion in the transverse direction, the board is enabled to move relative to the ball with at least a degree of spherical rotational freedom and also a degree of translational freedom in directions other than the vertical.

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. 2. Exercise apparatus according to claim 1, wherein the second lower portion is substantially co-extensive with the top portion in the longitudinal and transverse directions, the second portion having a through opening therein, the bounded portion consisting of that portion of the top portion that is exposed within the through opening. 3. Exercise apparatus according to claim 1, wherein the second lower portion comprises a wall member that depends from the substantially flat region on the underside of the first top portion, the bounded region consisting of that portion of the substantially flat region within and bounded by the wall member. 4. Exercise apparatus according to claim 1, wherein the board is integrally moulded from plastics material in a single piece. 5. Exercise apparatus according to claim 1, wherein the board is symmetrical about the longitudinal direction and also symmetrical about the transverse direction. 6. Exercise apparatus according to claim 1, wherein the wall defines a boundary with the shape of a flattened oval comprising a generally oval shape having ends that are flattened from true oval shape. 7. Exercise apparatus according to claim 6, wherein at least a portion of the top side of the board defines positions for a user's feet and the portions are provided with a surface constructed to resist slipping of the user's feet. 8. A balance board having a top side and an under side, the under side being arranged to be mounted on top of a ball with a user balancing on the top side, the board being shaped to define a generally longitudinal direction and a direction generally transverse to the longitudinal direction, the board being formed from a first top portion defining said topside and a second lower portion substantially co-extensive with the top portion in the longitudinal and transverse directions and being joined to the first top portion, the second portion having a through opening therein, whereby a substantially flat portion of the underside of the first portion is exposed, said substantially flat portion being bounded by a wall defined by said through opening, the distance across said substantially flat portion in the longitudinal direction of the board being greater than in the transverse direction, so that, with the said substantially flat portion balanced on a ball with a diameter less than the distance across the said substantially flat portion in the transverse direction, the board is enabled to move relative to the ball with at least a degree of spherical rotational freedom and also a degree of translational freedom in directions other than the vertical. 9. A balance board according to claim 8, wherein the board is symmetrical about the longitudinal direction and also symmetrical about the transverse direction. 10. A balance board according to claim 8, wherein the wall defines a boundary with the shape of a flattened oval comprising a generally oval shape having ends that are flattened from true oval shape. 11. A balance board according to claim 8, that includes a high friction layer secured to the working portion to resist slipping of a user's feet. 12. A balance board having a top side and an under side, the under side being arranged to be mounted on top of a ball with a user balancing on the top side, the board being shaped to define a generally longitudinal direction and a direction generally transverse to the longitudinal direction and havinga substantially flat region on its under side to which is mounted a wall member that depends from said under side and defines a working portion of said substantially flat region within and bounded by said wall,the distance across said working portion in the longitudinal direction of the board being greater than in the transverse direction, so that, with the said working portion balanced on a ball with a diameter less than the distance across the said working portion in the transverse direction, the board is enabled to move relative to the ball with at least a degree of spherical rotational freedom and also a degree of translational freedom in directions other than the vertical. 13. A balance board according to claim 12, wherein the board is symmetrical about the longitudinal direction and also symmetrical about the transverse direction. 14. A balance board according to claim 12, wherein the wall defines a boundary with the shape of a flattened oval comprising a generally oval shape having ends that are flattened from true oval shape. 15. A balance board according to claim 12, that includes a high friction layer secured to the working portion to resist slipping of a user's feet. 16. A balance board according to claim 12, in combination with a ball whose diameter is less than the distance across the said portion in the transverse direction. 17. A balance board according to claim 16 wherein: the wall defines a boundary with the shape of a flattened oval comprising a generally oval shape having ends that are flattened from true oval shape.
