abdominais...barriga...

Todos queremos ficar sem barriga, mas cuidado... porque para emagrecer é preciso um bocadinho mais de esforço!


Porcari's 2005 study in the Journal of Sports Science and Medicine, found that all 24 subjects who used the belt five days a week for eight weeks said their abs felt firmer and more toned. Stomach-crunch tests showed a strength gain — about 70% more than a control group. Lab measurements showed they lost more than an inch from their waistline, but they didn't shed body fat or drop pounds. The device could be especially helpful for people who can't do regular sit-ups, including people with back trouble, Porcari says. "But anyone who expects to look like the people in the infomercials will be disappointed."Claims of "1,500 sit-ups an hour" or "rippling muscles" from EMS are ludicrous, and no EMS device could dramatically flatten a stomach or speed weight loss, he says. A person needs to burn calories to lose weight, and it's not possible to burn significant calories through contractions alone. "You'd have to do thousands of actual sit-ups to lose any weight," adds Wayne Miller, an exercise physiologist at George Washington University. "Anyone who can do that many sit-ups probably doesn't need to."
