Get your family on an exercise program, the CDC advises. Find your child’s favorite activity and try to keep it up for at least 30 minutes. Work up to 60 minutes of physical activity most days of the week. Walk, jog, swim, ride your bikes or play soccer. Aim for at a moderate exercise level, meaning that you should be able to talk while working out for most of your workout. Try to include 30-second bouts of vigorous activity, where you are all moving as fast as you can, in your workout. Work out as a family or ask your child to bring along a friend to help her stay motivated.
