Turn your body into a high-powered fat-burning machine! If you see those words on a weight-loss website — especially if the site offers "secrets," "tricks," "simple rules" or other gimmicks that promise to make your fat melt away — you should be very skeptical. I'm not saying it wouldn't be nice if there were some kind of shortcut, but that's just not the way it works. I'll make it simple: When you exercise, you burn more calories than you do while sitting on the couch.

It gets cold where I live. But even when the forecast is for "hideous below zero" ? as some Canadians are fond of saying ? I'd still rather go outside than run on a treadmill. That should give you an idea of how much I dislike this particular piece of workout equipment. Nevertheless, in the past week I've found myself doing the hamster imitation because I find treadmills good for one thing: high-intensity interval training, or HIIT for short. In my last column, I busted the myth that HIIT burns a lot more calories than regular aerobic exercise done at a steady pace.

At some point most athletes want to hoist themselves another rung or two higher on the competitive ladder. For runners, cyclists and swimmers, elapsed time is the measure of success. In other sports, however, bursts of speed are needed for maximum performance, says Jeff Dilts, fitness manager at the Sports Club/Irvine and a competitive rower and swimmer. In full-court basketball, for example, a player might sprint up and down the floor 100 times during a game.

For years, Michelle Cuellar exercised five days a week. "But you wouldn't have known it by looking at me," says the 33-year-old mother of two. "I felt fit -- but I was still fat." No matter what Cuellar did -- run on the treadmill for 30 minutes at a time or attend the occasional spinning class or boot camp, her weight rose. By last summer, she carried 176 pounds on her 5-foot-6 frame. Then, last fall, for the first time in her life, Cuellar started shrinking.

Cross "too busy" off that list of excuses for not making it to the gym. If you can't fit a long workout into your day, you may be able to get the same benefits by working out harder for a shorter period of time. Sprint interval training, which combines repeated, short bursts of intense exercise with intervals of rest, has long been the domain of professional athletes, such as swimmers and track runners.

When it comes to cardio exercise, less appears to be more. That's the conclusion of researchers who discovered that extremely short bouts of high-intensity exercise produce the same improvements in muscle health as longer, more moderately paced workout sessions. In the two-week study, published in this month's issue of the Journal of Physiology, 16 college-age men, all recreational exercisers, were asked to exercise on stationary bicycles three times a week.
