An apparatus (600) and system are disclosed for manipulating soft tissue. The apparatus (600) includes a support member (602) having a support surface (606) disposed between a first end (608) of the support member (602) and a second end (610) of the support member (602). The support member (602) is elongated in a lengthwise direction (612) between the first end (608) and the second end (610). The apparatus (600) also includes a raised member (604) having an outer surface (614) disposed opposite an inner surface (616). The inner surface (616) is supportable by the support surface (606) of the support member (602). The outer surface (614) of the raised member (604) is configured to rotate along at least a portion of a user's body in response to movement of the raised member (604) along the user's body. The raised member (604) is repositionable along the support surface (606).
