I wouldn't worry about it too much, especially since there's not much you can do to spot reduce. I have the same problem in certain areas too. My hips, stomach and facial fat is quickly shrinking but my upper arms? My back? My calves? Pffft! Not a chance!

The consensus is that the newest fat comes off first; where as the older fat puts up a major fight. Only time (or lipo!) will slim down your trouble areas it seems.
