Research: Kids not getting enough exercise

Chances are your kids aren't getting enough exercise -- even your youngest ones.

Researchers monitored kids at 10 preschools. They found the children were only exercising about 12-percent of the time. The rest of their day was spent napping, eating, or generally being inactive.

The CDC recommends kids get at least one hour of daily exercise. The researchers point out plenty of exercise at a young age is essential for a child's development and for preventing obesity.
