Training, massage, regeneration: the fitness roller from the Viessmann Selection is a real all-rounder - it relieves tension and promotes blood circulation, increases mobility, stimulates the metabolism and strengthens the connective tissue. This self-massage roller made of EVA (ethylene vinyl acetate) consists of a green, hard interior and a black, soft outer roller and, thanks to its surface structure of nubs and flat areas, enables a targeted deep massage. The hydration of the fasciae surrounding the muscle (connective tissue) is stimulated, which improves mobility and regenerates the muscles faster. Exercise sessions to strengthen the deep musculature are also possible with the roller. The most effective exercises are printed on the package. A video tutorial is also available on the website of the manufacturer Schildkröt-Fitness.
