Using EMS for Strength

EMS, or Electrical Muscle Stimulation, has been used by athletes and Olympians for well over 30 years. Here at StimRx, we utilize state of the art muscle stimulation technology which forces muscle contraction using electric impulses. This safe and well-proven exactly mimics natural muscle contraction. As the stimulus occurs directly on the muscle it activates a much higher percentage of the muscle fibers than through normal exercising.

The History of EMS in Strength Training and Sports Medicine

EMS has been used for many years to augment and enhance muscle strength and performance. Likewise, studies conducted by Soviet sports specialist in the late 1970’s claim up to a %40 increase in force gains when using EMS. Since sharing these studies with western physicians and sports medicine experts, the use of EMS for strength training has become more widely accepted and ubiquitous. Accordingly, knowledge of the subject and the technology has advanced at a rapid pace since the 1970’s. In 2010, a study conducted by a world congress of researchers indicated: European Journal of Applied Physiology” url=”″

Strength training by [EMS] does promote neural and muscular adaptations that are complementary to the well-known effects of voluntary resistance training

This unit is for those who are a bit more advanced. Often used by doctors and chiropractors, the Power Stim 15R is one of the most powerful muscle stimulators in the world. This unit would be recommended for those who have already been working out and have a regular exercise routine.This unit is also great for those that need more power because they have a thick layer of body tissue.

This unit features a separate Russian stimulation button. This gives you some of the strongest frequencies available anywhere in the world -2500Hz.The Power Stim 15R has the world’s longest contraction time. Longer contractions have been tied to faster toning of the muscle. Only the Power Stim 15R contracts for a full 100 seconds.The Power Stim 15R provides ultimate user control allowing for the detailed setting of frequency, contraction and relaxation times. If you want full customization, this is definitely the unit for you.

Not Just any EMS

Many studies came to the realization that depending on the type of EMS used, different results can be accomplished. For example, EMS can be used to increase fatigue resistance, muscle endurance, and force production. Therefore, electric muscle stimulation needs to be scientifically engineered for the desired results and needs to come from a reputable EMS dealer. Because of these factors, our customers love our units because they are simple and easy to use. Many of our customers opt for the Powerstim 15R because of its power, customization, and efficiency when it comes to the activation of every muscle fiber.

In addition to using an EMS device for increasing muscle strength and performance, our units can be used for Warm-up and Recovery. Recent studies have shown that using EMS post workout will reduce pain associated with soreness, and speed up recovery time. By increasing blood flow into the desired area EMS helps remove harmful waste buildup, Increasing blood flow and oxygen which helps reduce inflammation, reduce pain and helps the desired area recover to its original state.
