Claims23
An exercise roller device, comprising:
- an outer roller comprising:
- a cylindrical-shaped center outer roller portion defining an outermost surface of the exercise roller device;
- and
- parabolic-shaped end outer roller portions provided at opposite ends of the center outer roller portion;
- and
- an inner roller supporting the outer roller, the inner roller comprising multiple inner roller portions assembled together, the assembled inner roller comprising parabolic-shaped end inner roller portions located at opposite ends of the inner roller,
- wherein the outer roller and the inner roller are configured so that a vertex of each parabolic-shaped end outer roller portion and a vertex of each parabolic-shaped end inner roller portion are located at each end of the exercise roller device and each vertex is located on a center longitudinal axis of the exercise roller device, and
- wherein a centered cylindrical-shaped outer portion is located with a centered circumferential groove located in the exercise roller device, the centered cylindrical-shaped outer portion having a diameter less than the cylindrical-shaped outer roller portion.
