HI-EMT works through the application of High Intensity Focused Electromagnetic energy (or HIFEM, for short). During an hiemt treatment, the Emsculpt applicator is used on the muscles. This applicator applies HIFEM energy to the muscles, causing them to have supramaximal contractions that are many times more intense than the contractions you induce during a work out. (Note: While these contractions are intense, they are not painful.) These supramaximal contractions cause the body to build muscle, just like they might after a workout. However, since these supramaximal contractions are more intense than the standard muscle contractions you experience during a workout, the body builds muscle more quickly.
