DENVER -- Sweating off the pounds might be a thing of the past with a new machine that promises to shed pounds simply by standing on it.

"You can stand on this machine for 10 minutes and it's equal to 45 minutes to 60 minutes of typical exercise," said DeepTone instructor Jennifer Ament.

Ament said TurboSonic uses sound waves that produce frequencies to stimulate your cells. She said a person can burn up to 300 calories in 10 minutes, and that's why people shouldn't be on it for more than that.

"It's equal to 60 minutes of exercise so you'd be just overdoing it," said Ament.

"I lost 9 pounds, a pants size, which is very exciting and I noticed my face tightening," said Kelly Walton.

Walton has been using the TurboSonic for seven weeks, usually once a week. It's already made a difference for her.

Greenwood Athletic Club's Dr. Neil Wolkodoff has been studying these frequency machines. He said the body vibration has been demonstrated to increase bone density, increase strength, increase balance, and even burn calories.

However, Wolkodoff said, for people trying to lose weight, they should combine other cardio exercises with TurboSonic.

"Most of the research that looked at whole body vibration said that they were at best mild cardiovascular effects, which means you're burning some calories just standing there but not the same thing as jogging around the block," said Wolkodoff.

DeepTone in Denver is offering the use of TurboSonic to its clients for a fee.
