Infants and toddlers:
  -  Get a little exercise in while they are napping with a home exercise video or machine such as a treadmill or stationary bike.
  -  Put them in the stroller and hit the road. A brisk walk will give you exercise and give the baby a little fresh air.
  -  Swing your partner. Toddlers love to dance, so put on some music and have fun burning calories.
  -  Go to the playground. Pushing a swing or see-sawing will help build muscle; build upper body strength by going hand-over-hand on the monkey bars.
  -  When your baby is old enough, buy a safety-approved bike seat and take him for a ride.
  -  Find a gym with good baby-sitting services.

Elementary-school-age children:
  -  Be "sports." Play catch in the backyard; kick around a soccer ball.
  -  Take long bike rides together.
  -  Get into the swim of things. When you take the kids to the pool, walk back and forth in the shallow water while your kids play nearby.
  -  Go shopping. Take the kids for a "mall walk." Walk around the mall several times while window shopping.

Adolescents and teens:
  -  Shoot hoops. Play a little one-on-one basketball.
  -  Learn a new sport. Sign up for tennis or golf lessons together; take karate or yoga classes.
  -  Register for a fun run (or walk).
  -  Implement regular family walks several times a week.
  -  Work together in the yard raking leaves, pulling weeds and planting flowers.
