Product Detail & Benefits


FDA Approved

Electrostimulation is not meant to be a replacement for traditional strength training exercises. However, electrostimulation does enable you to attain results that were previously unachievable through strength training alone. At best, electrostimulation is meant to be a complement to your existing sports training program. Athletes can utilize a methodology-based sequencing of different training techniques, including electrostimulation, to exploit their distinct and individual benefits for strength training.

The Performance US muscle stimulator is recommended for the fitness enthusiast and/or the athlete who engages in frequent competition. It features a total of five programs with five levels of progression to help competitive athletes achieve the highest level of performance.


The Compex Performance US, our newest Muscle Stimulator, is recommended for the fitness enthusiast and/or the athlete which engages in frequent competition. It features a total of 5 programs with 5 levels of progression to help competitive athletes achieve the highest level of performance.

The principle of electrostimulation is very simple and precisely reproduces the processes that occur when our brain orders muscles to contract. When we decide to contract a muscle, our brain sends a signal in the form of an electric current that travels at high speed along the nerve fibers. On arrival at its destination, the signal excites the motor nerve, which transmits the information to the area immediately around the muscle and triggers the muscle contraction. In the case of electrostimulation, excitation occurs directly on the motor nerve using electrical pulses perfectly adapted to guarantee effectiveness, safety and comfort in use. In fact, muscles cannot tell the difference between a voluntary contraction (triggered by the brain) and an electrically induced contraction: the work carried out is exactly the same. It's natural!

  • Recover faster and better after exertion
  • Improve stamina and endurance
  • Gain strength and speed
  • Work on continuity
  • Help increase your muscle volume
  • Help improve blood circulation
  • Stregthen ankles to avoid strain
  • Help improve your abdominal muscles

Enjoy all these benefits without osteotendinous constraint on the joints, mental fatigue, and cardiac stress.
