CA 2353132

An exercise device has first and second components with a hinge coupling the proximal ends of the components. The first component has a cone shaped distal region, a semi-cylindrical shaped proximal region, and a generally flat intermediate region. A recess is formed between the distal region and the proximal end. The second component has a thin disc-shaped distal region, a semi-cylindrical proximal region, and a generally flat intermediate region. The second component is positionable within the recess of the first component. An enlarged annular collar has a first half on the first component between the intermediate and proximal regions and a second half on the second component between the distal and proximal regions and has a radius of curvature greater than the radius of curvature of the proximal regions. A spring urges the first and second components into the open orientation during use.
