Effective and powerful. The Corefit I EMS training belt stimulates the central and lateral abdominal muscles with electrical impulses via 4 electrodes, thereby increasing the intensity of the training. There is a choice of 9 different EMS programmes for endurance, fitness and HIIT training, muscle and strength building and regeneration. The ergonomic shape of the belt and the flexible waist belt ensure a comfortable feeling while wearing it. The LCD display with clear symbols makes it easy to use.
