Making war on an incipient love handle

[ilya]

I am not overweight at all (5'8" and 146 lbs.) but I'm developing an ugly love handle. I hate it and I want to get rid of it. What's my optimal strategy?
I've been going to the gym 5-6x/week since the first week of January...I usually do a 45 minute aerobic bit at mid-150's HR, and sometimes lift some weights (but this is haphazard). I am in better shape than I was 3 months ago but the f'in love handle is not going away.

Help! Thanks.
