Top 10 Dumbest Fitness Gadgets and Fads

A vibrating dumbbell that, thanks to its suggestive back-and-forth motion, mainly became the butt of jokes and talk show parodies.

An office chair whose seat continuously spins in circles to train your abs while you type at your computer.

Silver plastic pants that claim you 'sweat away' fat, while you only lose fluid and overheat.

A rocking platform on which your knees spin around to 'melt away' belly fat, with mainly sore knees as the result.

A bizarre elastic face mask that supposedly prevents wrinkles and trains facial muscles, making you look like Hannibal Lecter.

A metal rod you were supposed to hold over your plate to magnetically pull fat molecules out of your hot meal.

A mechanical saddle for the living room that mimics trotting and galloping to stimulate your core stability.

Two loose plastic handles with a built-in counter, which basically comes down to simply jumping up and down on the spot.

Brands claimed special rounded soles trained your leg muscles while walking, which led to multimillion-dollar fines for misleading advertising.

A hinged device you had to squeeze with both hands, which once again led to hilariously awkward movements.
