The present invention relates to portable medium and low frequency muscle exercise equipment that produces regular and three-dimensional exercise effects over entire subcutaneous tissues and deep muscles in such a manner that an interference wave generated by interference between electricity having a frequency in a low frequency band and electricity having a frequency in a medium frequency band applies stimulation to various regions such as the subcutaneous tissues and the deep muscles. The portable medium and low frequency muscle exercise equipment comprises: a case a stimulation voltage generating module installed in the case to generate a stimulation voltage a frequency modulation module for modulating a frequency of electricity generated by the stimulation voltage to adjust stimulation strength a frequency generating module for transmitting the electricity having the modulated frequency to an electrode terminal an electrode terminal disposed on the case in an exposed manner to transmit the output electricity to human skin and a control module for controlling the operation of the above modules, wherein a plurality of electrode terminals are formed in pairs and separated, the frequency generating module outputs the electricity having a frequency in a low frequency band and the electricity having a frequency in a medium frequency band to a pair of electrode terminals in different channels respectively, so that the electricity having a frequency in a low frequency band and the electricity having a frequency in a medium frequency band, which flow through the human skin, cross each other and interfere with each other, thereby generating a beat wave.La présente invention concerne un équipement portable dexercice musculaire à basse et moyenne fréquence qui produit des effets dexercices réguliers et tridimensionnels sur lensemble des tissus sous-cutanés et muscles profonds de sorte quune onde dinterférence générée par une interférence entre lélectricité ayant une fréquen
