A self-massage apparatus includes opposed first and second rails, each having a first end, an opposed second end, and a length extending therebetween. A plurality of ball assemblies having opposed first and second ends spans the opposed rails and spaces the first and second rails apart from each other by a fixed distance. Each of the ball assemblies is one of an axle, or an axle, a ball mounted on the axle, and spacers flanking the ball, or an axle and balls mounted on the axle.
