Why would ab muscles need 500-1000 reps to build any mass? You need low rep high tension work. Lay on your stomach, toes bent like your going to do a pushup. Stretch arms up over your head, palms down. Tense and with your weight on your hands/feet contract and raise your body off the floor. Chances are you cant come close to doing it with your arms fully outstretched so bend your arms and bring your elbows in and support your weight on forearms. You want to find a position that you can only hold for about 3-5 seconds, do 3-5 reps and 3-5 sets.
