An exercise device having an insert slidably coupled within a base; a compression element (e.g., a helical spring) located within a cavity formed by the base and the insert; an extension element (e.g., an elastic band) extending through the cavity; and opposing handles connected to opposing ends of the extension element. When the device is in its equilibrium state with no external longitudinal forces applied to the handles, the spring is slightly compressed and the elastic band is slightly extended with the resulting forces keeping the components of the device together. When the opposing handles are moved closer together, the elastic band is relaxed and the spring is further compressed. When the opposing handles are moved further apart, the elastic band is further extended, but the spring is not relaxed.
