This device is used to stimulate muscle growth and fat burning. A gentle current stimulates the muscles, causing them to contract. And with time, more muscle fibers are activated, thereby building more muscle mass.
There are different types of EMS devices available on the market, but they all work in the same way. The device sends out low frequency currents which cause involuntary contractions in the muscles under treatment.
A typical EMS session might last anywhere from 15 to 60 minutes and it's safe for use at home or in a clinic.
