For me it's my lower belly... I have lower overhang that makes it so that I can't wear cute underwear, and I don't wear pants (I work out in pants covered by a skirt

heh). It makes it so that I have 54" chest, 46(?)" waist, 62" hips, so I wear very different sizes on top and bottom. I can't wait until the lower tummy is gone and I can run or jump up and down without hurting myself!
