There was a time in your life when you didn't even realize what you were doing was called aerobic or cardio exercise. One of the most successful long-term weight-maintenance strategies is to make sure you burn 1,000 calories through exercise every week. But how you burn them is up to you. You can do anything from playing basketball (400 calories an hour*) to a game of squash (790 calories an hour). There's no reason anything you do has to feel like a "workout."

1. Inline skate
Head for the sidewalk or boardwalk or, if it's cold outside, find an indoor skating rink (and think back to grade-school skating parties).
Burns up to 700 calories an hour, depending on your speed and how hilly the course is

2. Shoot hoops
At home, the local park or gym, play a game of basketball with a few friends.
