Well, you're right that your abs were giving out and your lower back was jumping in to help out, but we don't want to allow that to happen. When you feel yourself unable to maintain posterior pelvic tilt, you either have to correct your pelvic position or terminate the set.
Does that answer your question? Or do you want me to go into a long explanation of what anterior/posterior pelvic tilt is?
