everywhere! I mean I have a small back and small arms but thats about it! My back is 34 inches and I am 145 but my hips stomach butt there is just so much fat and though I see the # going down on the scale I'm not noticing it going down on the measureing tape :(. I'm going to continue until 20 days is complete so I only have 2 weeks left but I really hop by then its a bigger difference! I acutally feel like I look bigger then I am :(
