At home

5. Do two chores at once. Put dinner in the oven first and do the laundry
while it cooks or make an extra-large meal for leftovers later in the week. Either way, you're freeing up another hour of workout time.

6. Really walk the dog. Instead of the usual, speedy poop-scoop, take him on a 15-minute walk -- good for you (and for him). Twice a day equals a half-hour of exercise.

7. Clean your home. If a grungy floor doesn't move you to do some weekend cleaning, maybe this will: You'll burn about 215 calories* cleaning (vacuuming, mopping, etc.) for just an hour.

8. Go for a sunset stroll. Walk off some of your dinner: Even a leisurely, 30-minute walk burns approximately 140 calories.
