Experts agree that getting the proper amount of calcium and at least 40 minutes of exercise every day are the best ways for children to prevent bone problems later in life. To help motivate your kids, we've rounded up six fun ways to incorporate calcium-rich foods and fitness into their daily routine.

Make minor changes to morning meals. Switch to calcium-fortified orange juice, melt a piece of reduced-fat cheese on hot chapatti, or top waffles with yogurt instead of syrup or jams and jellies.

Just add chocolate! Chocolate milk is full of calcium and vitamin D, and kids love it! Manufacturers call for two tablespoons powder per cup of milk, but you should cut back to 1 or 1 1/2 tablespoons to reduce the amount of calories and sugar. Also, avoid no-sugar-added chocolate powders or "light" syrups because they contain artificial sweeteners, which aren't appropriate for most children.

Serve up a healthy scoop. Kids love ice creams, Don’t they! Treat your child to a small serving of lowfat or whole frozen yogurt or ice cream and top it with fruit. One creamy 1/2 cup serves up all the calcium in one cup of fat-free milk (300 mg) for the same number of calories (90). Garnish with dry cherry, peach slices or other fruit.

Take a hike! Walking is not only a terrific source of fresh exercise-it's also a great way for families to bond. Encourage your child to help by making trail mix, filling water bottles, and studying maps.

Set the wheels in motion. Go for a family bike ride before or after dinner -- it will give you even more time to catch up on the events of the day.

Get grooving. When the weather requires your child to stay indoors, turn her on to an exercise video which teaches kids the Twist, the Jitterbug, and other dances in an easy-to-follow format and even provides on-screen song lyrics so kids can sing along.
