Slack Off For More Energy

By Michael Roizen, M.D., and Mehmet Oz, M.D.

Been trying to overcome the irresistible force of couch gravity, but just don't have enough giddy-up to go? No, you don't need a personal trainer -- or a workout that makes you sweat more than a tubful of ice in Honolulu. Instead (slackers, rejoice), light, easy exercise may do more for your energy levels than the hard-core stuff.

The evidence: When nonexercisers do low-intensity workouts -- like light pedaling on a stationary bike for 30 minutes three times a week -- you reduce tired-all-the-time feelings by as much as 65 percent. And it only takes six weeks of light workouts for you to feel pepped up. Moderate-intensity workouts boost your energy levels too, but not as much.

You don't need a bike or a gym. Just put on your walking shoes and a watch (clothes are good, too) and time yourself for 30 minutes. Paying attention to time is more important than obsessing over how many miles, steps or blocks you've walked because, for example, it keeps you from pushing too hard or going too slow if you've over- or underestimated the distance.

So what's the explanation for the better energy boost you get from easygoing activities? If you're out of shape, vigorous workouts tone you up but also tire you out. So if you're just trying to get off the couch, start slowly. When whatever you're doing starts to feel too easy -- you'll know -- that's when it's time to kick things up a notch.
