Most muscle contractions occur when the brain sends a signal through your central nervous system to instruct your skeletal muscles to contract. These muscles come in pairs, one to move your bone in a particular direction, and the other to move it back. Unlike internal organs and cardiac muscles, skeletal muscles are voluntary, meaning that they require a trigger (such as a brain signal) to activate.
Full-body EMS devices combine the advantages of conventional strength training with EMS technology. Users wear a “suit” that maps a series of built-in electrodes to each of your major muscle groups. The low-frequency impulses that serve as the basis for EMS actively engage all muscle groups simultaneously, rather than placing single electrodes on individual muscle groups. With these impulses, the muscles are engaged much more intensively, multiplying the effects of any exercise.
