slowly getting there

Options
This year I lost 42 pounds but it seems I lost most of it in my butt. This is getting frustrating. I need to lose my belly as well. At lost of it I lost before joining on here. How do I lose the belly fat? I have 100 more to go or so. I make small goals to help me lose the weight. i really want to get to 160 by my birthday next year. Which is in april. Any ideas would be great. I have walked and I have do sit up and push ups.
