Lead your kids in physical activities
Be a positive role model and lead your kids in physical activities on a regular basis. We dont mean army-style workouts, but rather enjoyable activities everyone in the family can do. Take your family on a hike through the woods, a bike ride through the neighborhood or to a nearby hill for some sledding. Your kids will love your participation and will begin to seek out more of these outings and activities. To make it extra fun, invite another family to join you on your romps.

Work activity into your day
Not all physical activity has to be a planned event. You can work activity into your day just doing routine household chores. The key is to do whatever needs to be done energetically.

If the family car is looking dingy, get out a hose and bucket and challenge the kids to wash it in a certain amount of time. If they succeed, reward them with a trip to the park.

Instead of you cleaning the house at night after the kids are in bed, take an hour after dinner to clean it together. Assign each child a specific job, crank-up some fun music and encourage everyone to complete their duties with gusto. The whole house will get clean quickly, you'll all get a bit of a workout, and you'll enjoy the satisfaction of a house where all the rooms are tidy.

Limit time spent in front of screens
While everyone likes to relax after a busy day, watching TV or playing a video game should not be the day's main event. Allow kids screen time after they've been active for a solid chunk of time. Also, don't put TVs, computers or video game systems in your kid's bedrooms. They can easily log long hours at these screens while you're busy doing other things.

Encourage participation in live-long sports
Encourage your kids to be active now (and all their lives) by giving them the gift of competence in life-long sports such as tennis, martial arts, skiing, etc. When kids get involved in these kinds of activities at a young age, they tend to become accomplished rather quickly, giving them self-confidence and motivation for staying active in these sports their whole lives.

Support your kids in team sports
Your child does not have to play on the most competitive team around. It's enough for him or her simply to participate and reap the rewards of physical activity and team camaraderie. Many towns have club-level teams, where there are no tryouts and everyone gets to play. And you never know if your child might have a hidden athletic talent you haven't seen yet!

Many of the things parents do to keep everyone physically active have the added benefit of strengthening family ties, so parents can feel good knowing they're helping the family both physically and emotionally.
