1. An exercise device comprising: a support plate;a retaining element coupled to the support plate and defining a cavity;a roller member defining a diameter and being partially received within the cavity and configured to be rotatable relative to the support plate about at least two axes of rotation; anda plurality of bearings engaged with the roller member, the roller member being rotatable relative to the plurality of bearings, the plurality of bearings being spaced about the roller member to form a first ring about a portion of the roller member, the first ring defining a diameter less than the diameter of the roller member;the roller member having a defined circumference;the support plate circumnavigating at least a majority of the defined circumference of the roller member. 2. The exercise device recited in claim 1, wherein the retaining element includes a retaining wall generally conforming to the outer surface of the rolling member. 3. The exercise device recited in claim 1, wherein the plurality of bearings are housed in a joint housing. 4. The exercise device recited in claim 3, wherein each joint housing houses one of the plurality of bearings. 5. The exercise device recited in claim 3, wherein the joint housing comprises a cylindrical body with a first closed end, and a second open end, comprising a collar. 6. The exercise device recited in claim 5, wherein the collar has a circumference greater than the body. 7. The exercise device recited in claim 1, further comprising a handle connected to the support plate. 8. The exercise device recited in claim 7, wherein the handle comprises an opening extending from the first face to the second face. 9. The exercise device recited in claim 1, wherein the roller member is spherical. 10. The exercise device recited in claim 1, wherein the retaining element defines a lip to retain the roller member within the cavity. 11. The exercise device recited in claim 1, further comprising an end cap disposable over the roller member to cover the roller member. 12. The exercise device recited in claim 1, wherein the roller member is configured to roll along a rolling plane, the roller member defining a middle plane and an upper tangential plane, both of which are spaced from, and parallel to the rolling plane, the upper tangential plane being tangential to the roller member and spaced from the rolling plane, the middle plane being positioned halfway between the rolling plane and the middle plane, the plurality of bearings being positioned between the middle plane and the upper tangential plane. 13. The exercise device recited in claim 1, wherein the plurality of bearings form a second ring about a portion of the roller member and spaced from the first ring, the second ring defining a diameter less than the diameter of the roller member. 14. The exercise device recited in claim 1, wherein the plurality of bearings are spaced from the support plate. 15. The exercise device recited in claim 1, wherein the plurality of bearings form a second ring about a portion of the roller member and spaced from the first ring, the second ring defining a third circumference less than the first circumference.
