You said you were on the same routine for 12 months? Many times, I've found increasing intensity by changing to a different workout or very challenging physical sport has "shocked" my whole body into adapting, the side effect being those abs you're talking about.
First off, you shied away from cardio, so of course it would be more difficult to get those "abs" you want.
Second, an example of an increased intensity would be doing interval training, sprints, all-court basketball, swimming, high volume lifting, 5x5 program, etc.
Just find a new challenge for yourself.
