Features 1、MICROELECTRICITY: While traditional exercise communicates microelectric signals to the muscles to contract through the brain, the abs band drives the muscles to contract themselves by simulating biological microcurrent stimulation. 2、MULTIPLE USES: When using the abs exercise band, you can workout sitting, standing, or even lying down, you can use it anytime, anywhere. 3、EFFICIENT CALORIE BURN: Microelectrical stimulation makes workouts more efficient and burns up to 3 times more calories than other abs belts. 4、CONVENIENT: It automatically recognizes the position of the muscles and releases the stimulation at a fixed point for precise abs training results. 5、ALL ROUND WORKOUT: Can fully activate the muscle lines and help you build muscle, so that the muscles can be effectively worked out, while shaping the tight abdominal muscles to show the perfect line.
