i don't think lots of reps is working too well.. i want bigger abs! My bodyfat is not high at all and i can see them a little, but i want to bring em out more... so i guess i will hit the weights with em to start shocking my abs into growing.
throw abs with weights in 2 days aweek and another 2 without weights and bet you'll see a difference.they're also right about the diet part,but you say you already have low bodyfat so hit em' with weights.
super girl...here's something that has worked wonders for my girlfriend...she,just like you,has low bf and needed to bring them out...it's her fourth week on this program and her abs are very visible at the moment...
4 sets of 12-15--leg pulls(on low pulley) (4-0-1)
3 sets of 12--machine crunches (3-0-1)
1a-3 sets of 12-15--standing garhammer raises (2-0-2)
1b-3 sets of 15-20--weighted crunches (2-0-2)
note:1a and 1b are supersets...use 60 sec rest between sets...use bwt at first and add weight if necessary to add to the resistance.
