I got some decent ones, I have been working out for around 12 years off and on ( 9 years religiously) and I have been doing abs properly for the last year or so.
Its not hard to maintain as long as you eat properly
You need a low bf % in order to make out your abs, many people have at least decent abs who dont even do ab workouts. Its because of how they eat, looking ripped is %90 diet and %10 working out
You will however, have much bolder abs the more you train them. And just crunches ect wont make your abs "pop", you need to put them under weighted excercises in order to have them jump out of your stomach.
Be sure to do varying excersises as well, as your abs are divided into numerous sections, and if all you do is one type of excercise, your abs will not be balanced
Now wheres Cebseb??? When the topic involves weights or graphic nudity, he shows up immediately.
