Every bit of exercise counts, so take steps to add action to your day, suggests fitness expert Liz Neporent, author of Fitness Walking for Dummies and The Fat-Free Truth. Since you’re more likely to stick with gradual changes, add just one new calorie-burner per week with her month-long schedule below.

Week One: Anytime you take an elevator, get off three floors early and use the stairs.

Week Two: Instead of e-mailing a colleague, walk to his or her office and talk in person.

Week Three: Chat with a friend on a cell phone while taking a 10-minute walk.

Week Four: Do 10 jumping jacks after various activities in your day, such as brushing your teeth, loading or unloading the dishwasher, and setting up your coffeemaker.
