Now, utilizing its new dual stability rollers (DSR), the Rolflex Pro sets the bar even higher. Unlike anything else on the market, the Rolflex Pro—a pressure-based therapy tool—focuses on muscular tension with a more balanced approach and pinpoint accuracy. The DSR enhancement allows an individual to concentrate their foam rolling around extremely hard to reach joints, such as the knee and elbow, more than traditional devices. With the Rolflex Pro users get all the added benefits of the dual stability rollers without compromising portability. Just toss it in a bag, brief case or back pack and self-massage anywhere, anytime with the ability to foam-roll over 95 percent of the body.
