EMS massage is a function of an electrostimulator that uses Electrical Muscle Stimulation (EMS) technology for muscle relaxation and regeneration. Unlike strengthening programs that induce strong muscle contractions for training purposes, massage programs work with gentler, lower-frequency impulses. These impulses cause slight muscle twitches and vibrations that mimic the effects of a classic massage. The goal is to improve blood circulation in muscle tissue, support the removal of waste products such as lactic acid, and provide overall relaxation for tense or tired muscles after a sports performance or a demanding day.
