The benefits of Electronic Muscle Stimulation and the use of Muscle Stimulators gained world-wide popularity in the 1970’s when Dr. Yaakov Kots of the Soviet Union applied EMS in the training of his Elite Olympic Athletes, resulting in strength gains up to 40% higher than normal. This revelation “shocked” the conventional strength training world and from that point forward the term Russian Stimulation was born.

It was at the 1976 Montreal Olympics,  That Dr. Kots disclosed his techniques and results concerning the use of electric muscle stimulation training for his USSR Olympic Athletes. The electric current he used was called the Russian Current or Kots Current. This special frequency of 2500 Hz would eventually become known as Russian Stimulation or Russian Stim. His studies showed that his current was effective in building muscle strength and size and increasing fast twitch response for speed.

Better Results Faster

EMS, or Electrical Muscle Stimulation, has been used by athletes and Olympians for well over 50 years. At FlexTone we utilize state of the art muscle stimulation technology, which forces muscle contraction using electric impulses. This safe and well-proven method mimics natural muscle contraction. As the stimulus occurs directly on the muscle, it activates a higher percentage of the muscle fibers than through normal exercising. 

Full muscle activation increases exercise tolerance, which, in turn, enhances and accelerates physical performance, meaning better results, faster.
