Slimline Slimming Machines electrically stimulate and firm your muscles. It is a simple, safe and painless alternative to surgery or drugs, while providing quick results, including reduction of cellulite, and improvement in body and skin tone. During the exercise, a computer-controlled electrical message is transmitted to stimulate the selected muscle groups. When the electrical signal is applied directly to the muscle, the muscle will contract until the signal is removed, creating large energy demand on your muscles. This causes the surrounding fat to be burned for energy. The more powerful the strength of the signal, the harder the contraction will be. This is known as an involuntary muscle action, as it happens without the brain asking the muscle to contract.
