High Energy Focused Electromagnetic Wave technology For more photos, please visit: http://www.en.mandaladayspa.hu/videogallery HIFEM stands for High-Intensity Focused Electromagnetic technology, and is a non-invasive and painless method used for its fat-breaking and muscle-building effect. The device causes rapid muscle contractions by high-energy focused electromagnetic waves. Medical research has proved that after completing a course of treatment, HIFEM can effectively increase the muscles by 16% and reduce fat by 19% at the same time.
