No, we're not pitching a miracle diet or other weight-loss gimmick you'd see on late-night TV.

But the reality is that you CAN burn more calories while you sleep -- or when stting at your desk, in front of the television or in other various states of inactivity. The key is to increase your resting metabolic rate (RMR). And the best way to do that is through strength training.

By working out with weights regularly, you increase your lean muscle mass. And lean muscle burns calories at a much higher rate than fat does. The more lean muscle you have, the more calories you'll burn -- even when you're staying perfectly still.
