Abstract: 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.
