RAD Rod Massage Tool. The RAD Rod is the ultimate tool for flushing muscles of waste products and breaking up tough and unforgiving tissue. The RAD Rod was designed to be used on the larger muscle groups of the body, mainly the muscles of the legs. Unlike many other stick style rolling tools, the RAD Rod keeps things simple with a streamlined approach: a thin diameter that offers less surface area and therefore more pressure, plus the ability to work precisely into small spaces. Its stainless steel core offers no nonsense control at every level of intensity you could ask for. Use after use, the RAD Rod reigns supreme over flimsy, flexible stick alternatives because it doesn't bend, break, or give in when you give it your all. This sturdy build empowers you to dominate areas with thick tissue such as hamstrings and quads, or you can lighten up and use it on the usual suspects, like your calves, back, and IT bands. Just because the RAD Rod is steel tough doesn't mean it doesn't also have a sensitive side, however. A thin, 360 degree layer of soft, EVA material pads the length of the RAD Rod to give you the freedom to use it anywhere from thick, meaty leg muscles to more delicate, boney areas like the shins and forearms.
