Don t Hold Your Breath...

This may sound like a no "brainer",  but how often do you find yourself holding your breath when you are strength training?  Your core muscles need oxygen to work at full capacity, so be sure that you keep breathing.  As a general rule, you want to inhale on the easiest part of the move (on the way down from a crunch) and  exhale when you have to exert the most force (on the way up on a crunch).
