BLACKROLL® posture trainer – designed by SWEDISH posture – is an easy-to-use and simultaneously very effective tool for improving your posture every day, during sports, or at work. The BLACKROLL® POSTURE can be worn discreetly on the body using Velcro or attached over the clothing, and is easy to adapt to any size. Even on first use, the POSTURE significantly improves body awareness. The back trainer automatically brings the upper body into a straight posture, extending the chest muscles. Positive side effect: Oxygen uptake is increased with the posture trainer, supplying the muscles with more energy. Your breathing also becomes deeper and more efficient.
