The Body Sculpture ball duo BB0122 massage roller is ideal for massaging the paraspinal muscles. Thanks to the indentation in the middle- it perfectly adapts to the shape of the back, which guarantees ease and effectiveness of the massage. Now you do not have to worry about back pain after a hard day. The device is lightweight- small in size -so you can carry it with you in a purse or backpack and use it whenever you need it. The product is not too hard- so everyone can use it. It will be useful both for relaxing the muscles and warming them up and preparing them for physical exercise. When using the roller- it is important to roll slowly and carefully - moving it over specific muscle groups. It should be remembered that one part of the body should not be massaged for longer than 3 minutes. The roller should be placed along the muscle fibers. When you hit a painful point during massage- hold the roller in this place. For the massage to be effective- remember to place the roller on a hard surface.
