Today marks the 13th annual Family Health and Fitness Day, which is meant to encourage families across the US to trade time spent in front of the TV or computer for outdoor family activities, like a neighborhood walk or hike. Why? Walking is one of the easiest and least-expensive ways to combat obesity and illness.

One way to inspire your family to walk with you is to make it fun. Walking can be enjoyable for everybody — just use your imagination. Here are some creative ideas to use on your next family walk:

Create a reward system. Keep track of the distance everyone walks and award prizes for goals reached. For example, reward your little ones with toys that encourage activity — like bubbles, Frisbees, bouncy balls, or a jump rope — even if they walk just a few blocks. These inexpensive gifts will keep them moving long after the walk has ended.

Walk to the beat. Sure, chatting is fun, but family walks don't need to revolve around conversation to be fulfilling. If your teenagers seem reluctant to walk with you, tell them you wouldn’t mind if they listen to their favorite music on their MP3 player — it might be just the thing to get their feet moving.

Play a game. As you and your family walk, try playing a game that involves the changing scenery. "I Spy" and "20 Questions" are fun for young children. You can also plan a scavenger hunt involving objects commonly found along your walking path — like pine cones, maple or oak leaves, or rocks of certain shapes or colors — and have your whole family participate.

You'll no doubt find that your family will be happy to spend some quality time together. And who knows, getting outdoors for a walk may become a long-lasting family tradition that will keep you and your family fit and healthy. Happy walking!
