Toning tables may help relax tense muscles, but they certainly don't work
your muscles, which is what you must do to burn calories. Other gimmicks
such as jiggling belts, rollers that "knead" fatty areas, electrical muscle
stimulators, body wraps or suits, and the like, do not promote calorie
burning. Some of these devices (like body wraps or sweatsuits) do cause
fluid loss (sweating) which results in lower weight and body measurements,
but these losses are fleeting. A couple of glasses of water, and you're
right back where you started.
