The Road Map
Choose your moves: For this workout, you'll complete three 5-minute circuits, for a total of 15 minutes from start to finish. First do 30 seconds of cardio (run in place with high knees, do jumping jacks, or jump rope), then select one exercise from each category -- lower body, core, upper body -- to complete in the remaining 4:30. Complete two more circuits right away, choosing a new combination of exercises each time.
In half the time it takes to watch an episode of "The Office," you'll burn calories, improve circulation, work up a light sweat, and enjoy a halo of energy for the rest of the day. But perhaps best of all, "You'll feel better about yourself because you've accomplished something," Anderson says, which may be more than you can say about your holiday shopping.
