Complementary training program for the development of hard muscle groups. In addition to the overall stimulation of the body (recommended for accelerated blood circulation), intense training of a specific muscle group is obtained during the 20-minute session. The varying stimulations of deep muscles produced by the microprocessor-connected also help to move difficult muscles (joint injuries, poor muscle function, slow development). In one-sided sports disciplines, the muscles on the other side are easily overlooked. Such an imbalance also occurs in everyday life, whether for work or simply genetically. As a result of a non-movement lifestyle, certain muscle groups, especially the supporting muscles, in many cases shorten and therefore deformations may occur throughout the entire muscle. Electro-muscular stimulation may be the solution to this problem, since it is focused on specific muscle groups.
