Abstract
Abstract A device for exercising or developing balance, the device including a rockable support member provided by arcuately formed supports, a rotatable cross bar extending between the upper ends of the supports with the bar being selectively rotatable and the bar carrying a support plate upon which the user may stand. The support plate is also rotatable. The combined, available movements between the rockable support member, the rotatable cross bar and the support plate provides a tri-axial possibility for the user. The rotatable bar is lockable in a non-rotative position or limited rotation or full rotation.
