Obesity is on the rise among America’s kids. According to a report by the Center for Disease Control, "Physical inactivity has contributed to an unprecedented epidemic of childhood obesity that is currently plaguing the United States." Regular exercise can play a major role in helping kids manage their weight.

How much exercise should my kids get?

All kids can benefit from exercise, even if they are overweight or uncoordinated. In fact, physical activity may be helpful in improving the physical and psychological well-being of kids with a weight problem. The American Heart Association has made the following recommendations:

• Kids age 5 or older should participate in at least 30 minutes of moderate intensity activity each day.
• If kids can’t engage in a continuous 30 minutes of physical activity each day, try to provide at least two 15-minute sessions or three 10-minute sessions instead.

What can I do to make sure my kids gets enough exercise?

It is up to parents, teachers and coaches to encourage kids to be physically active. Here are some ways you can help improve your kids' physical fitness:

• Educate your kids about the importance of good nutrition and physical fitness.
• Set a good example by being physically active yourself.
• Plan family activities that include physical activity. Walk to the park and have a picnic lunch with your family or go on a bicycle ride together in the evening.
• Limit the amount of time your kids spend in front of the television or computer.
• Encourage your kids to participate in school and community physical activity and sports programs.
• Become an advocate for quality school and community physical activity programs.

Is it possible for my kids to get too much exercise?

Kids with distorted body images may rely on exercise as a way to lose weight. This condition is prevalent in females, but can also affect males. Kids who exercise excessively may suffer from an eating disorder, such as anorexia nervosa or bulimia nervosa. Excessive exercise can damage your kids' tendons, bones, and joints. It can also result in muscle loss, especially if your kids are not eating properly. If you recognize any of these warning signs in your kids, contact your family physician right away.

Here are some warning signs to look for in your kids:

• They won't skip a workout, even if they are sick or injured.
• If they do miss a workout, they exercise twice as long the next session.
• They don't appear to enjoy working out, but feel obligated to continue.
• They skip seeing friends and ignores responsibilities to have more exercise time.
• They are constantly preoccupied with their weight and appearance.
• They are never satisfied with their physical achievements.
