Phil and Amy Parham, contestants on The Biggest Loser: Families, offer fresh ideas from their book, The Amazing Fitness Adventure for Your Kids.

Create a chart.
Much like a kids’ chore chart, a get-fit one lets you track activity and award points when family members play a sport, ride their bikes, even walk to a friend’s house. This can encourage some healthy competition. At the end of the month, the one with the most points can choose a prize for the family from a list of options, like a trip to an amusement park or a night at the movies.

Track steps.
Give each family member a pedometer and explain how it works. Using one regularly may encourage everyone to walk more daily. At dinnertime, take time to look at your numbers and talk about the mileage and what it means to overall fitness. As the kids up their walking, consider signing up for a walk-a-thon—so you can all be active as you give back.

Make adjustments.
It’s great that you bring your child with you for a walk around the school track—but all she wants to do is go home. That’s because small children are more inclined to exercise in spurts, not the long stretches adults can manage. When you hit the track, bring a scooter, a bike or even a ball she can bounce to keep her busy as you walk. This way you’ll get fit together.
