The E-FIT EF-1280 equipment is using EMS technology (electric-muscle-stimulation) for a whole body stimulating workout which means that the entire body is stimulated simultaneously throughout the training sessions. While doing exercises and sports the messages of the brain are transmitted through the nerve-tract by electrical impulses to the motor controls of the muscles. The EMS technology (electric-muscle-stimulation) delivers electrical stimulation to the muscles in direct proximity, causing them to contract and relax as if we were exercising.
