Again, I have a VERY different view lol
I havent done direct ab work since the 80's.
All I have done is standing press, squats, deadlifts, rows, benches.
I can do a 1 arm superman pushup, its actually easy, and a superman pushup with a 20kg plate on my ass.(hardest thing I've ever done)
None of this shoulders pinched back superman pushup, full extension.
Ab roller and planks is all I get my clients to do, plus the above mentioned exercises.
Even after not training for 2 years I was still able to do stacks of superman pushups.
Gareer, your a novice, I think, if you ask a question, and a guy that lifts much more weight than you gives you an answer, dont simply question him and give your view, he may know more than you.
Load 230kg on your back and walk out from a squat rack, see how that feels on you core. One guy that gave you an answer actually squats that, do you reckon he might know something?
