What happens is that more muscle fibers contract and relax at this “biologically special” rate. And that’s where the BionicGym “magic” comes in. Impulses through the BionicGym wraps stimulate the motor-neurons (nerves-to-muscles) in the legs and gluteal muscles (bum), telling them to contract repeatedly. (The muscles relax or lengthen by themselves).
By inducing enough muscles to actively contract at optimal rates, they shout out for blood to supply oxygen and energy. When that happens, your heart pumps harder and faster to deliver this blood.
The result is that BionicGym trains both your cardio system and your muscles. You become more breathless and in time heat up – even sweat. After all, shivering is nature’s way of warming you up by burning calories.
