The Addaday Bioscillator takes foam rolling to the next level. Addaday designed the dynamic vibrating massage roller to alleviate pain and soreness in hard-to-treat areas, like your hips, shoulder blades and glutes. The lightweight, portable roller uses oscillating technology to boost the power of traditional foam rolling. You can use the peanut-shaped Bioscillator to help treat tennis elbow, soothe sore feet and work out knots in your hips and glutes. Coated in a non-slip rubber exterior, the device is easy to use and won’t slide around on the floor. Studded with rounded bumps, the Bioscillator will work deep into muscles for relief where you need it most.
