About EMS

Electronic Muscle Stimulation (EMS) belts are waist trimmers designed for firming and toning the abdominal muscles. You just place the belt on your abdomen, and it will do the job for you. You can actually see your abs working out.

The principle behind EMS is simple. Electrical nerve impulses are sent to your muscles, causing them to contract and then relax. They will become firm due to that contract-release action, just like the one you do at the gym while working out.

You will not get electrocuted, though. The belts contain gel pads with electrodes, but they are very well cushioned. They will not touch your skin at all. These EMS devices have been very well thought through, so do not worry.

There are several waist trimmers on the market. Here are two of them that are most promising. They are both of high quality and deliver the best results.

Flex Belt Review

The Flex belt is an FDA approved EMS device that is meant to tone and strengthen the abdominal muscles using electric impulses. According to a recent study, this waist trimmer is the most efficient on the market.

Their only alternative is an EMS device, and what better recommendation than Flex Belt?
