Can't seem to find the time, energy, or commitment to exercise? You're not alone. Nearly 41 percent of Americans don't meet the minimum exercise goals -- 30 minutes of moderate exercise most days of the week -- recommended in the Dietary Guidelines for Americans.

If you don't get up and get moving, do you know that you share the same increased risk of coronary heart disease as cigarette smokers, people with high blood pressure, and those with high cholesterol? It's true, so as soon as you can, please step away from the couch!

The key is to get moving. Most exercise benefits come from simply doing more than what you're doing right now. Forget the 'perfect' program. Just get up off of that couch. All it takes to reduce that risk is a simple 30-minute stroll around the neighborhood at least five days a week. That half-hour's worth of moderate activity also cuts your risk of stroke. If you're under time constraints, don't let the 30-minute rule prevent you from getting started. You'll still get the same fitness benefits if you break up that half hour into smaller chunks of time. Three 10-minute walks or two 15-minute flurries of activity will work just as well.

Think of it this way ... all it takes is 10 minutes of moderate activity, three times a day, to cut your risk of coronary heart disease.
