1. A base for use on a treadmill, the base comprising:
three or more first ball bearing assemblies, each of the three or more first ball bearing assemblies comprising a ball and a mounting assembly; and
one or more lower ball bearing assemblies, each of the one or more lower ball bearing assemblies comprising a ball and a mounting assembly;
wherein each of the one or more lower ball bearing assemblies extends downwards from a plane defined by a subset of three of the first ball bearing assemblies, the lower ball bearing assemblies projecting further downward from the plane than the first ball bearing assemblies and of a vertical projection of the one or more lower ball bearing assemblies onto the plane intersects a triangle with vertices located at the first ball bearing assemblies of the subset of three, thereby allowing the base to pivot in multiple directions around the one or more lower ball bearing assemblies when placed on a flat surface.
