Foam roller exercise device

Abstract

A foam roller exercise apparatus is disclosed. In one embodiment, the foam roller exercise apparatus may have first and second portions. The first portion may have a uniform cross-sectional shape, a first curved outer surface having a first radius of curvature, and a second curved outer surface spaced from the first curved outer surface and having a second radius of curvature. The second portion may be separable from the first portion and may have a uniform cross-sectional shape complimentary to the first portion. The foam roller exercise apparatus may have a third portion.
