Patent ID: 7137926

Claim:
An exercise device comprising an elongated roller formed of a compressible material and having first and second axes, a length and a sectional plane parallel to the first and second axes, the sectional plane dividing the roller into first and second portions, the first portion having a first convex outer surface that is curved about the first axis, the first surface having a first curvature with a first radius of curvature, and the second portion having a second convex outer surface that is curved about the second axis, the second surface having a second curvature with a second radius of curvature, the first and second surfaces intersecting each other, the length being substantially greater than the distance between the first and second axes, the first curvature being different than the second curvature, and wherein the first curvature is circular and the second curvature is circular, the radius of the first curvature being different from the radius of the second curvature.
