Electrical muscle stimulation (EMS) is a non-invasive body contouring treatment that improves muscle building and fat burning. Through the high intensity electromagnetic therapy procedure one can enlarge current muscles, as well as grow new muscle fibers. The procedure can be performed on the abdominals, buttocks, arms, calves and thighs. When using EMS, your body’s muscles will contract 400 times in one 30 minute session. That is the equivalent of doing 400 crunches or squats in a single session.
