The Corefit II EMS abdominal and back belt ensures an even more effective workout thanks to electrical muscle stimulation. Two electrodes on the abdomen and back provide additional stimulation to the muscles with impulses. There are nine different EMS programs available for endurance, fitness, and HIIT training, muscle and strength building, as well as recovery. Additionally, the intensity of the impulses can be adjusted as desired. The ergonomic shape of the belt and the flexible strap ensure comfortable wear.
