A balancing board is disclosed with a base and an elongated deck including a top surface; longitudinal and central lateral axes; and a bottom surface, which includes at the central lateral axis a center post mounting mechanism. The base's bottom side rests on a support surface. The base's top side has a top surface and is rotatable with respect to the bottom side at a rotational bearing. A center post is fixed at its bottom end to and extends upwards from the base's top surface, and has at its top end a pair of roller posts extending laterally and horizontally from the center post at opposing sides. Each roller post rotationally mounts a roller, extended downwardly from the roller post, below the center post's top end. The center post mounting mechanism engages with and aligns each roller with the central lateral axis on opposing sides of the longitudinal axis.

1. A balancing board for a user to use on a horizontal support surface, the balancing board comprising: an elongated deck having a top surface, a bottom surface, a longitudinal axis and a central lateral axis, the bottom surface including, at the central lateral axis, a center post mounting mechanism;a base having a bottom side adapted for resting on the horizontal support surface and a top side, the top side rotatable with respect to the bottom side at a rotational bearing;a resilient center post fixed at a bottom end thereof to the top surface of the base and extending upwardly therefrom, the resilient center post having, at a top end, a pair of roller posts each of the pair of roller posts extending laterally and horizontally therefrom at opposing sides thereof, a pair of cylindrical rollers each of the pair of cylindrical rollers rotationally mounted on one of the pair of roller posts and extending downwardly therefrom lower than the top end of the resilient center post, the center post mounting mechanism of the elongated deck engaged with the pair of cylindrical rollers such that each of the pair of cylindrical rollers is aligned with the central lateral axis of the elongated deck on opposing sides of the longitudinal axis of the elongated deck;whereby with the bottom surface of the elongated deck contacting the resilient center post and captured thereon with the center post mounting mechanism, the elongated deck is free to move within a predetermined range in a lateral plane and in a forward/backward plane, as well as in the directions of roll, pitch, and yaw. 2. The balancing board of claim 1 further including a pair of tilt brakes each fixed with the top side of the base and having a disengaged position that does not inhibit flexing of the resilient center post or roll or yaw of the elongated deck, and an engaged position that inhibits flexing of the resilient center post and roll and yaw of the elongated deck. 3. The balancing board of claim 2 wherein each of the pair of tilt brakes include an elongated member pivotally fixed with a hinge at a lower end thereof with the top surface of the base and at an upper end with an elongated deck engagement surface. 4. The balancing board of claim 1 wherein the center post mounting mechanism includes a pair of U-bolts each fixed to the elongated deck at the bottom surface thereof, each pair of U-bolts straddling the central lateral axis of the elongated deck on the opposing sides of the longitudinal axis and on opposing sides of the resilient center post, each of the pair of U-bolts capturing one of the pair of cylindrical rollers between itself and the elongated deck. 5. The balancing board of claim 1 wherein wherein the base further comprises a bottom plate and a top plate, wherein the bottom plate has the bottom side and the top plate has the top side, the rotational bearing being fixed between the bottom plate and the top plate and allowing the top plate to rotate with respect to the bottom plate. 6. The balancing board of claim 1 wherein of the bottom side further includes at least one high-traction foot for frictionally engaging the horizontal support surface. 7. The balancing board of claim 1 wherein the pair of roller posts are integrally formed from a single metal rod that traverses a roller post aperture extending laterally through the resilient center post proximate the top end thereof. 8. The balancing board of claim 1 wherein each of the pair of roller posts includes a roller stop proximate a distal end thereof to maintain the pair of cylindrical rollers on the pair of roller posts. 9. The balancing board of claim 1 wherein the top surface of the elongated deck includes a non-slip texture. 10. The balancing board of claim 1 wherein the elongated deck includes two handle indentations in the bottom surface thereof at opposing ends thereof. 11. A balancing board for a user to use on a horizontal support surface, the balancing board comprising: an elongated deck having a top surface, a bottom surface, a longitudinal axis and a central lateral axis, the bottom surface including at the central lateral axis a center post mounting mechanism;a base having a bottom plate having a bottom surface, a top plate having a top surface, a rotational bearing being fixed between the bottom plate and the top plate and allowing the top plate to rotate with respect to the bottom plate, the bottom surface adapted for resting on the horizontal support surface;a resilient center post fixed at a bottom end thereof to the top surface of the top plate of the base and extending upwardly therefrom, the resilient center post having at a top end a pair of roller posts each of the pair of roller posts extending laterally and horizontally therefrom at opposing sides of the resilient center post;a pair of cylindrical rollers each rotationally mounted on one of the pair of roller posts and extending downwardly therefrom lower than the top end of the resilient center post, the center post mounting mechanism of the elongated deck engaged with the pair of cylindrical rollers such that each of the pair of cylindrical rollers is aligned with the central lateral axis of the elongated deck on opposing sides of the longitudinal axis of the elongated deck;the center post mounting mechanism including a pair of U-bolts each fixed with the elongated deck at the bottom surface thereof, each of the pair of U-bolts straddling the central lateral axis of the elongated deck on opposing sides of the longitudinal axis and on opposing sides of the resilient center post, each of the pair of U-bolts capturing one of the pair of cylindrical rollers between itself and the elongated deck; anda pair of tilt brakes each fixed to the top surface of the top plate of the base and having a disengaged position that does not inhibit flexing of the resilient center post or yaw or roll of the elongated deck, and an engaged position that inhibits flexing of the resilient center post and yaw and roll of the elongated deck;whereby the elongated deck is free to move within a predetermined range in a lateral plane and in a forward/backward plane when the pair of tilt brakes are disengaged, as well as in the directions of roll, pitch, and yaw. 12. The balancing board of claim 11 wherein the bottom surface of the bottom plate further includes at least one high-traction foot for frictionally engaging the horizontal support surface. 13. The balancing board of claim 11 wherein the pair of roller posts are integrally formed from a single metal rod that traverses a roller post aperture extending laterally through the resilient center post proximate the top end thereof. 14.
