Electric muscle stimulation (EMS) is touted as having the ability to strengthen muscles, reduce weight, minimize body fat and improve local blood circulation. During physical activity, your brain (inside source) sends a message to nerves to signal the contraction of certain muscles. EMS uses an outside electrical source to communicate with nerve fibers. When the stimulation is applied, the brain sends a nerve impulse to the motor point of the muscle. This signal causes the muscle to expand and contract. Livestrong
