Rogue’s DT Tempering Rollers were co-developed with powerlifting legend Donnie Thompson—creator of the Thompson Fatbell, the Fat Pad, and the Belt Squat Belt—among many other innovations. In his South Carolina gym, Thompson has helped introduce “body tempering” as a heavy-duty upgrade over traditional foam rollers, utilizing weighted cast-iron cylinders to break up trigger points and relieve tightness in the joints, muscles and fascia. Rogue has refined those original prototype cylinders into our 24" DT Tempering Rollers, available here in 50 LB, 80 LB, and 110 LB increments. Compared to other massaging rollers, the substantial weight of the DT Tempering Rollers can create a much more intense form of soft tissue mobilization, without causing any additional pain or discomfort in the process. All of these rollers are made from powder-coated cast iron, and feature recessed ends that act as the handles, enabling easier handling and control. Color-coded bands are included in the center of each roller (indicating the weight) and at both ends (featuring Rogue branding) for easy identification from a distance: Green = 50 LB, Gray = 80 LB, and Yellow = 110 LB.
