Since the basic nature of correct ab function is isometric, the exercises in which the abs perform this function will provide exercises for the abs as well. This may seem childishly apparent, yet virtually every strength coach adds extra concentric/eccentric ab work to the program anyway. The thinking must be that just squatting, deadlifting, pressing, cleaning, snatching, chins, and barbell curls – all of which involve trunk stabilization as a critical performance component – do not provide sufficient ab work by themselves. I disagree.
That's Mark Rippetoe, one of the premier strength coaches in North America.
I don't see why there's this idea that squatting and pulling heavy is going to make you massive all over. There's a kid at the university of Western Ontario who pulls over 700 and weighs just over 215 at like 6'1? It's not really inefficient to get that big, I mean if you can squat 500 lbs for reps, and are cut as fuck? I don't see why that's a problem, you'd look pretty decent. There shouldn't be this attitude that you can't be strong AND look good. Hell once I'm done with football I'd have NO qualms with dropping 20 lbs of fat and getting into sub 10% range for BF. Bitches would fucking LOVE it.
