Step up to the plate
Seeing you take fitness seriously is likely to boost your kid's interest in exercise, now and in the future. Gina Dudley and her husband love to run together, but when their daughters were 6, 4, and 2, the Bloomfield, New Jersey, parents couldn't always snag a sitter. Their solution: Running laps on a local track while the girls played their own run-around games in the center. Other family workouts:
Run or walk fast alongside a toddler or preschooler who has learned to ride a bike or tricycle.
Pop in a yoga or workout video. Your baby or toddler can bop around while you work up a sweat.
Let your preschooler be your trainer. He can count your crunches, time how long you're on the treadmill, and judge whether you should stretch just a little further.
