Blackroll Fascia Roller Set Booster Standard: Promotes circulation and activates muscles. The Blackroll Fascia Roller Set Booster Standard includes the innovative vibration core Booster as well as the Standard fascia roller. The foam roller is water-insoluble, disinfectable, and suitable for all applications due to its average density. The Vibra Motion Technology of the vibrating, removable core provides oscillating, high-frequency vibrations for a significantly more intense massage effect. These can relieve muscle tension and fascia adhesions even in deeper tissue layers and promote faster muscle recovery. The frequency can be individually adjusted at the push of a button depending on the application area and goal. The high frequency irritates pain receptors and results in a treatment of trigger points that is perceived as significantly more pleasant—especially for those who are experiencing fascia rollers for the first time.
