You're lying on the sofa, maybe munching a bag of chips, and watching your favorite movie on DVD.  And ... you're toning your abs? That's the picture painted by some proponents of passive exercise, a fitness trend based on the idea that you can pretty much do nothing and still work out, if you have the right equipment doing the work for you.

But could this really work? WebMD asked three experts to offer up their opinions on four of the top passive exercise trends: whole-body vibration, chi machines, electronic ab stimulators, and inversion boots. So grab that bag of veggie chips, prop up your feet, and read on -- their answers might surprise you! 

Whole-Body Vibration

By far the most popular new addition to the passive exercise category is whole-body vibration or WBV -- also known as "Power Plate" exercise.  An outgrowth of a program used to train Russian cosmonauts, it quickly spread through Europe and Japan, then hit U.S. shores -- with whole centers now devoted to this workout.

How It Works: According to physical therapist and personal trainer Ben Quist, DPT, most people stand on the platform with knees bent at about a 30-degree angle, while the surface beneath their feet vibrates an astounding 30 times per second. 

That vibration, says Quist, tricks the body into thinking you're falling. "This, in turn, activates the 'stress reflex' -- an extremely rapid muscle contraction," says Quist, owner of Form and Fitness, a Milwaukee health club and rehabilitation center, where he has been training patients on the Power Plate for over a year.  These muscle contractions, says Quist, are responsible for most of the benefits attributed to this type of exercise. 

The Promise: According to manufacturers, those benefits include increased circulation, muscle strength, and flexibility; better range of motion; core conditioning and stability; and faster muscle recovery after working out. They say the health benefits also include enhanced metabolism, increased bone mineral density, reduction of the stress hormone cortisol, elevation of human growth hormone levels, and improved lymphatic flow. Whole-body vibration is also said to reduce cellulite and stimulate collagen production for smoother skin. Manufacturers also say MBV can provide muscle toning and conditioning for those who have health restrictions that keep them from exercising, such as multiple sclerosis, Parkinson's disease, and some forms of arthritis.
