What about abs?

What type of Fitness system claims they don't do abs?  The kind that is concerned with developing your functional fitness.  What Coach meant when he made this statement is that CrossFit does not encourage exercises that work the abs in isolation from the rest of the body. Isolating your abs and working them without knowing how their development fits into the big picture of how your body performs is really missing the mark.  Abs and ab strength are but a portion of "core strength".   Aesthetics are really where the benefit of crunches end.  Working movements like the overhead squats will help you look and perform more like an athlete.  Functional movements that require you to stabilize the mid-line will help with injury prevention and help reduce pain and improve posture.  These are benefits that we can all appreciate.
