Got fat? Got two weeks? Then I've got a plan for you. Well, the plan actually belongs to the folks at RealAge. I'm just passing it along.

It's a simple plan, and it works like this: Whatever you do for exercise (walk, bike, run), just mix in a few short bursts of high-intensity effort. It can up your fat-burn rate by 36 percent in just a couple of weeks.

Sustained, moderate exercise has fat-burning benefits too, but new research indicates that interval training is better. Consider this: When moderately-active women did a 60-minute cycling workout with four-minute bursts of high-speed pedaling and two-minute rests, they significantly bumped up their fat-burn after just 14 days. Time to amp up your routine, don't you think?
