1. An omnidirectional rolling apparatus for performing strength training exercises, comprising:
- a hemispherical stationary support frame, the frame comprising a top cover and a bottom cover;
a first rigid ball mounted between the top and bottom covers with a low- friction bearing system in between the ball and the top cover, the first ball having a first weight;
a hemispherical outer shell attached to the top cover, the shell having a gripping surface and being dimensioned so that a user can grip the rolling apparatus with one hand; and
a strap that is secured to the shell;
wherein the bearing system reduces rolling resistance when the rolling apparatus is loaded over a support surface during exercise;
wherein the first ball is freely rotatable in any direction on the support surface when loaded; and
wherein the low-friction bearing system comprises a plurality of ball bearings and a retainer for retaining the ball bearings within the bearing system.
