The Flex Belt

This device uses electronic muscle stimulation (EMS) to send electronic signals to your muscles, causing them to contract. Although this is an FDA-approved technology, it is not without controversy or detractors. Back in 2002, several ab exercise products like this were slammed by the Federal Trade Commission for false advertising, with claims these belts could help you achieve “washboard” abs.

Further, the only highly-cited study regarding the effectiveness of EMS belts dates from 2005 out of the University of Wisconsin, La-Crosse. Even that study admitted that subjects “did not lose any subcutaneous fat.”

Wearing The Flex Belt does provide stimulation. You can certainly feel it doing something. Unless you already have a good physique, however, The Flex Belt will not help you slim down. Those who The Flex Belt helps most – those already with a toned stomach – are the people who need it the least. Alas, a closer read of The Flex Belt’s official website does show a focus on abdominal muscle toning, and not belly fat reduction.

See this article about the effectiveness of “slimming” belts.

Gel Pads

The Flex Belt requires “gel pads,” which means your $199 investment in the system also requires you to continually purchase these pads as well. 1 set of Flex Belt gel pads costs about $15. Purchasing additional sets results in additional savings.

Fake Reviews

What is perhaps most disturbing is that legitimate, objective reviews of The Flex Belt are difficult to find amid questionable “press releases” and “reviews” – which end with glowing endorsements and links to buy the product. If you look closely at the links to purchase the product, however, you’ll often find they are affiliate links, meaning the person writing the press release or review gets a cut when someone purchases the belt from their link.
