You are doing a great job!!! Keep at it girl, 13 inches is a lot and like Calvin said, it's being replaced with muscle, which will help you burn more and more!! I'm there with you and I have a long way to go. Just on my second week of Insanity, but love it! It's awesome that you are sticking with it too, I hope to do the same thing. Keep us posted and congratz on the 13 inches!!! AWESOME JOB!!!
