You will never have to buy another EMS/Electrical Muscle Stimulator, Russian Stim, or Tens Unit again. Our units have been used by athletes and Olympians for well over 30 years. At FlexTone we utilize state-of-the-art muscle stimulation technology, which forces muscle contractions using electrical impulses. This safe and well-proven method mimics your natural muscle contraction. The stimulation occurs directly on the muscle and activates a higher percentage of the muscle fibers than normal exercise. This increases blood flow and releases endorphins. Our new 2024  Powerstim 15R  allows you to dial in the treatment you choose for Pain Relief & Rehab or Strengthening & Toning.

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.
Today the PowerStim 15R unit gives you the ultimate control allowing frequency specification, contraction and relaxation time. It is almost impossible to outgrow the strength a professional grade Muscle Stimulator like the Powerstim 15R and the settings can be learned in about 5 minutes. The user manual makes it simple.

Most people will feel immediate pain relief. If your goal is muscle strength and toning you will see and feel a difference within a few days of use.

Some advanced athletes do use the unit to warm up their muscles before they workout but its really not practical. Many Gym owners buy our  Powerstim unit so that they can treat customers dealing with chronic pain.
