Abstract:
In an implementation, a roller system is provided. The roller system includes a modular frame. The frame includes a plurality of weight component attachment points. Each weight component attachment point is adapted to receive one or more weight components such that a weight of the frame and location of a center of gravity of the frame is adjusted by the addition of one or more weight components to each of the plurality of weight component attachment points. The frame further includes at least one arm assembly adapted to connect to the frame, and to apply force to a surface, wherein the force applied to the surface is proportional to the weight of the frame and the location of the center of gravity of the frame.
