What it is
In electrical muscle stimulation (EMS), electrodes on the skin send weak electrical impulses that make the muscles contract. EMS is used in rehabilitation to build up or maintain muscle strength, for example after injury or surgery, and to train the pelvic floor. In body shaping, EMS is used to tone the muscles of the abdomen, buttocks, thighs, calves, arms and face. The effect on body shape is moderate.
