If you have Blue Cross, Blue Shield / Anthem health insurance, be sure to take advantage of their Blue Points program.  Blue Points is a way to manage fitness activities and earn points for great prizes.  The program is available for both kids and adults.  My kids love tracking their activities, ordering prizes, and what kids doesn't love to get a gift in the the mail?  The program is free to members, and requires little time to manage.  We love it!
