Weight loss: Aerobics
beats lifting weights

People who want to lose weight are better off running than lifting weights — or even than doing both, researchers at Duke University say.

The researchers compared people who did aerobic exercise — running, swimming, walking, for instance — with those who did resistance training such as weightlifting and with people who did both kinds of exercise. Those who got up and moved burned the most fat, they said in the Dec. 15 Journal of Applied Physiology.

“Given that approximately two-thirds of adults in the United States are overweight due to excess body fat, we want to offer clear, evidence-based exercise recommendations that will truly help people lose weight and body fat,” Leslie H. Willis, an exercise physiologist at Duke Medicine and the study’s lead author, said in a statement.

The news might be disheartening to a whole trendy cohort of exercisers who have become enamored with resistance training, often in combination with aerobics. Resistance training does have benefits. Research has shown it improves glucose control, for one thing. And then there’s the look of those six-pack abs to consider.

Participants were randomly assigned to one of three groups: resistance training of three days a week or about 180 minutes; aerobic training of about 12 miles a week or about 133 minutes; or both.

The groups assigned to aerobic training and aerobic plus resistance training lost more weight than those who did just resistance training.
