Anybody have any good/favorite exercises for obliques. I have the usual lower abs weakness, but I know much of that is diet, but my obliques aren't quite as thick as I would like. What exercises could help me build them up?

Lol, I wish I lived in colorado or somethin and could go snowboarding all the time. I'd take that workout any day. Only done it a few times, but it's definitely something I'm gonna do every winter!
DB Side Bends; Take a 60-70lb DB and drop the dumbell below your knees, and then straighten and focus on contracting you opposite obliques. Do 10 of these at a reasonable tempo like 3/0/x .
