 Kathy Ireland for the Will Rogers Institute. Are you worried that your kids aren't spending enough time being physically active? The best fitness is family activity. Ride bikes, play soccer, or just take a walk through the neighborhood. The important thing is to get your children moving with you. For more information on family activities and fitness, call the Will Rogers Institute. Call toll-free 877-957-7575 or visit wrinstitute.org and find us on Facebook and Twitter.
