| According to a recent University of Southern Maine study, 30 minutes of weight training burns as many calories as running at a blazing six-minute-per-mile pace for the same amount of time. (And it has the bonus of building more muscle tone than running.) What's more, unlike aerobic exercise, lifting weights has been shown to boost metabolism for up to 39 hours after you finish your last rep. Interval training—short, all-out sprints interspersed with periods of rest—has yielded similar benefits. For optimal results, do a total-body weight-training workout three days a week, resting at least a day between sessions, and do intervals on at least two of the off days. |
