Boosted metabolism can be reached in three ways with KICK IT Body fitness EMS training. Low-frequency stimulation can increase local blood circulation which results in an increased metabolic rate and increased lymphatic circulation. Using medium frequency stimulation a higher caloric burn can be achieved. Strength or muscle development training (using higher frequency stimulation) is extremely important as well: the more muscle someone has, the higher the resting metabolic rate becomes and therefore the more effective the fat burning will be.
