Justfit is a muscle electrostimulation device suitable for training, therapeutic purposes, aesthetic and skin modeling treatments. Healing with nature’s energies is as old as humanity. Hippocrates already recognized and applied the possibility of stimulation therapy using electric fish (eel, stingray, catfish). The theory of the mechanism of action was clarified in the 1960s. Subsequently, the development was determined by applying the results of microelectronics. Justfit technology opens up new horizons in the possibilities of stimulation therapy, as the use of the device helps prevent skin blemishes, muscle underdevelopment, weight gain and musculoskeletal problems.

Electrical muscle stimulation (EMS) uses electrical current to induce muscle contraction. This contraction is different from traditional exercise, which is controlled by the central nervous system. The stimulus in the motor neuron (action potential) caused by the nervous system or by the electrical impulse is the same. Therefore, the work of the muscle will be similar if stimulated at the same level. The muscle cannot actually distinguish whether the stimulus was initiated by the nervous system or by an electrical impulse. The nature and extent of the stimulus depend on the parameters set on the device.

Simply put, the Justfit device can do what the brain can’t. While the brain can stimulate most muscle fibers, the device can stimulate nearly 100% of them, so it can achieve greater synchronization between the fibers. Furthermore, unlike the human brain, the EMS device works the muscles with consistent, quality impulses without overloading the cardiovascular system or causing psychological fatigue. This produces better and safer performance gains than traditional training alone.

In summary, through correct stimulation with the Justfit device, the human body is not only able to increase and condition the muscles, but at the same time regenerates, renews itself and initiates self-healing processes.
