walking

So I have walked again today, another 6 miles, so thats 30 miles since last week, things had better start toning up soon. I just wish the bit at my hips would go, the bit where my apron folds over. I can breathe it in perfectly fine, but as soon as I put my knickers on then my leggings , the knickers go under it, the leggings go over and it just creates a lump then whatever I wear you can see it. Its my most hated thing about myself. So really hoping walking works. My fitness pal says I use up 590cals doing that, so surely I will start noticing soon.
