An exercise apparatus comprising:
- an outer handle having a longitudinal axis;
- a rod arranged at least partially within the outer handle and configured to rotate within the outer handle;
- a first weight plate comprising a first plate opening at an upper region of the first weight plate;
- a second weight plate comprising a second plate opening at an upper region of the second weight plate;
- a first bolt configured to extend through the first plate opening to couple the first weight plate to a first end of the rod;
- and
- a second bolt configured to extend through the second plate opening to couple the second weight plate to a second end of the rod,
- wherein each of the first weight plate and the second weight plate is a monolithic plate having a fixed mass, and
- wherein a center of mass of each of the first weight plate and the second weight plate is arranged off-center from the outer handle.
