One of the most popular weight loss and fitness products this year is the Slendertone Flex Belt, an electronic muscle stimulator. EMS devices, like the Flex Belt, work by training the muscle fibers via electrical impulses that evoke the contraction and release response in the muscle. The Slendertone Flex Belt actually uses a patented muscle stimulation technology. You simply wear the slender device around your abdominals and it does the work for you.

NFL Allstar Jerry Rice says of the Flex Belt, “It works those muscles, tones them, makes them stronger, and it is very easy.”

If you watch television in the wee hours of the night or morning, you have probably come across the infomercials for electronic muscle stimulators like The Flex Belt or the Slendertone.

So just what are these fitness devices that combine technology with exercise?

Electronic muscle stimulators (EMS) are actually much older than you might think. The concept was developed back in the eighteenth century as a way to stimulate changes in the muscle for therapuetic medical reasons. EMS devices work by training the muscle fibers via electrical impulses that evoke the contraction and release response in the muscle.
