![]() ![]() But recent research shows a new perspective. In fact, if you go by the numbers you find that even golfing beats out a light circuit workout. It’s well documented that an activity like moderate jogging burns more calories than weight training, an activity that’s highly anaerobic. ![]() There’s one argument for aerobic exercise that’s always been rock solid. Picture it in terms of liposuction: The whole point is simply to remove unattractive flab, right? That’s exactly what you should demand from your workouts. (Can you say “skinny-fat”?) However, if you weight-train as you diet, you protect your hard-earned muscle and burn extra fat instead. That 25 percent may reduce your scale weight, but it doesn’t do a lot for your reflection in the mirror. Research on low-calorie dieters who don’t lift shows that, on average, 75 percent of their weight loss is from fat and 25 percent of it is muscle. “For the same amount of exercise time, with diets being equal, the participants who lifted lost almost 40 percent more fat.” The weight they lost was almost pure fat, while the other two groups shed 15 pounds of lard, but also gave up 5-plus pounds of muscle. But the lifters shed 5 more pounds of fat than those who didn’t pump iron. The results: Each group lost nearly the same amount of weight-about 21 pounds per person in 12 weeks. One group didn’t exercise, another performed aerobic exercise 3 days a week, and a third did both aerobic exercise and weight training 3 days a week. ![]() In one study, Volek and his team put overweight people on a reduced-calorie diet and divided them into three groups. So if you’re told that running is ideal and you start dropping pounds once you take it up, then you have no reason to believe otherwise.”īut Volek’s research gives him good reason to doubt the conventional wisdom about the superiority of aerobic exercise for fat loss. “It’s sort of like a self-fulfilling prophecy,” says Jeff Volek, Ph.D., R.D., an exercise and nutrition scientist at the University of Connecticut. But if you’re looking to shed fat, the newest weight-loss research will tell you to look elsewhere for your exercise routine. Hundreds of studies since then have reported that aerobic exercise offers many benefits, from improving markers of heart-disease risk to coping with mental stress to enhancing cognitive function. This bestseller popularized the notion of running to improve health and lose weight, and it’s widely credited with kicking off the jogging boom of the 1980s. That’s when Jim Fixx’s The Complete Book of Running was published. In fact, you can practically pinpoint the year this idea started to take hold: 1977. ![]() For decades, we’ve been told that the best activity for burning calories and fat is aerobic exercise. ![]()
