1. Lead by Example. When it comes to exercise, an adult couch potato effectively nurtures a child couch potato, who then becomes yet another adult couch potato years down the road - a vicious cycle of inactivity that increases disease risk. Fortunately, the opposite is also true, so get off the couch and show your kids the value of an active life filled with physical activity.

2. Unplug for Awhile. Hours on end of TV, video games, and even phone and computer "activities" like instant messaging, chat rooms and other pursuits leave very little time for exercise. While there's no easy solution, establishing a daily time limit on these activities is a great start.

3. Find the Time. When we're young, we spend hours in the yard or on school grounds playing our favorite games; then we slowly get more and more responsibilities and somehow, the time just seems to disappear. It happens quickly, right around the time daily homework comes along. What can you do about it? It's the same advice, whether young or old: Find the time. Pencil physical activity into your child's daily schedule and don't let "life" ever erase it.

4. Make It Fun. Too often, exercise becomes more of a chore than a pleasing activity, and this often begins at an early age, basically as soon as children get involved in the rigors of organized sports. Sure, it's never all fun and games, but exercise shouldn't be a dreaded activity, not if you do it right. Be creative and teach children that active is fun at any age.
