Patent attributes
An exercise device including a base plate having a generally circular wall extending upwardly therefrom to define a base body having an interior cavity. Spaced apart roller assemblies are disposed within an interior of the base body. A generally convex dome of a motion platform assembly is at least partially disposable within the base body so as to contact the roller assemblies. The motion platform assembly slides, tilts or rotates as force is applied to an upper support platform. A lip of the motion platform assembly may contact a rim of the wall to limit a range of motion of the motion platform assembly. One or more elastic cords extending between the base body and the motion platform assembly provide resistance to motion of the platform assembly.
