Everything reputable I've read or heard is that you can not target one area over another. You can work on toning your behind, and the muscles will grow, but the fat won't disappear from that area.
I think just do what you are doing with diet and maybe start excercising more and, now that your belly is smaller, the fat will come off somewhere - like your behind or hips :)
Congrats on the work you've done so far!
UTA - just noticed you are from Decorah, IA - lots of my extend family live in that beautiful, small town. You probably know some of them, but I won't go into that! I won't be there, but my mom, sister and aunt will be there for Nordic Fest this year :)
