The TechSlim™ EMS function creates muscle contractions that can be quick and frequent, fast with long pauses, or contractions that are held for several seconds or minutes at a time. Normally, it is your body that fires your muscles by sending electrical impulses from your brain through your central nervous system (CNS). But an EMS device allows you to engage in deep, intense, and complete muscular contractions without actually activating (or stressing) your CNS—not to mention your joints and tendons.
The coolest thing is that your body doesn’t know the difference between a voluntary contraction and an electrically stimulated one. Your (silly) body only recognizes that there is a stimulus and reacts to it accordingly.
