What is EMS?



EMS is an initialism that stands for “Electrical Muscle Stimulation” and refers to a training method that has been trialed for decades and frequently used for health and fitness purposes. It is also referred to as electrotherapy. Low-level, but still effective external electrical impulses activate the muscles and cause the muscle fibers to contract.

The full-body training systems developed based on this method, which have been available since the early 2000s, enable almost complete activation of all the main muscle groups and provide an extremely effective method of training. Just two 20-minute training sessions per week is equal to working out for several hours in the conventional way, e.g. in a gym.

Whether you are looking to improve your health, get stronger, improve your endurance or develop a stronger, more attractive body – myostyle will help you to achieve your personal goal!

How does EMS work?


Before the electrical signals reach your muscles and cause them to contract, the current first needs to overcome the resistance of your skin. The following principle applies here: The higher the frequency – i.e. the greater the number of impulses per second, measured in the unit herz – the easier this resistance is to overcome.

Many EMS systems use low-frequency (LF) impulses that are significantly lower than 1000 hertz (Hz). The skin resistance represents a significant barrier for this frequency, which means that the impulses do not penetrate as deep. This can result in an unpleasant effect in which the low-frequency impulses feel like little pinpricks while training.

In contrast, modern EMS training systems like myostyle use modulated medium-frequency (MF) currents that are significantly higher than 1000 Hz. These faster impulses penetrate more deeply into your musculature and have a much greater effect. This leads to something referred to as the “volume effect”, which enables higher and more intense levels of stimulation. This results in stronger muscle contractions and better effects from training. At the same time, the higher frequencies generally make the training experience feel much more pleasant.


All of the advantages of modulated medium-frequency current at a glance

  • Highly effective muscle activation
  • Simultaneous tissue activation: cell metabolism is stimulated
  • Volume effect: all tissue structures are targeted
  • Depth effect: signal integrity is retained deep into the musculature

A large number of studies have investigated and proven the effectiveness of electrical muscle stimulation. You can also find an overview of EMS studies in our studies summary.
