tested only for already Foam Roller

The technique with the knobs is already painful in the beginning and at the first exercises to get in front like a medieval torture device. So who has not tried to advance on the Blackroll or the like, and tried here a "cold start" to lie, the first is only pain. For those who have gathered in the foam rolling and for some time to train with predecessors such as the Black-roll, this is a successful intensification of myofascial relaxation. The only thing that's really borderline until today, the femoral side is to train on the tract, as I have until today bruises.
