Exercise comes in different forms -- some not so unpleasant

But being physically active doesn't have to be unpleasant. Physical activity doesn't have to take place in a gym to count. And it doesn't have to mean you're training for a triathlon. It should be something you enjoy. That means walking, dancing, skating, cycling and paddling a canoe all count. So do the more mundane activities of daily living like vacuuming, washing and waxing the car, and raking leaves. It's even better if you make it a family affair and jump rope or play tag with the kids, throw a Frisbee for the dog or plan an active vacation. Whatever it takes that makes exercise less objectionable.

To reap the benefits, you should do at least 30 minutes of moderate-intensity activity most days of the week. Translation: At least four days a week, spend at least 30 minutes doing something that leaves you feeling a little winded. Ideally, you should keep moving for an hour, but some activity is always better than none.
