Shelli!!! How are you doing? I have bad knees and the only thing that keeps me going is the hope that they won't hurt so much when I am 70 pounds lighter! But boy do I like sitting! haha. The fitbit has been a great motivated but not nearly as much as this website! I hope you will post and keep us informed! I am really nervous b/c this is my first challenge. LET'S DO THIS! we have 14 days! WE CAN DO IT TOGETHER!!
