The intensity of your exercise is more important than how long you do it when it comes to keeping weight off.

Just a few extra minutes of brisk activity can help protect you from obesity. Less than 5 percent of us get the recommended level of physical exertion each week.

Research shows that short, but high intensity exercise still benefits the body mass index. Each extra minute decreased the odds of obesity by from 2-5 percent.

The study is in the American Journal of Health Promotion.
