Abstract: A power flex ring system having a plurality of rings of semi-rigid elastomeric material, each ring having an initial shape, the plurality of rings interconnected to form a ring chain. A user handle is adapted for connection to a selected one of the rings to form a first chain end. A securement mechanism is adapted to connect to a selected one of the remaining rings to form a second chain end and to secure the second chain end to a fixed structure, wherein the handle, the chain and the securement mechanism are structurally configured to facilitate an exercise motion by a user exerting a force via the handle to deform the plurality of rings from their initial shapes. Each of the plurality of rings has a selected tensile strength and a different color indicating the tensile strength of the rings.
