Neoprene Gym Belt Training Belt RX-3 【Wide Belt】M size. Used at a home gym 2-3 times a week for about 3 months. I am selling it because I upgraded to a power belt. There is slight rust on the metal parts of the RX3 belt, but there is no problem with use, so please understand that. Please refer to the official page for the size of the belt. Please purchase with the understanding that this is a used item.
