How do i BUILD abdominal musicle?

ok i already have a flat stomache and im very lean and healthyalso you can kinda of see 6 seperate musicles on my absbut besides crunches what are some good exercises i can do NOT to lose fat and calories and such (you can include those though if they're good)
but to build up on what i already haveoh and so far i do 100 cruches a day about 5-6 times a week to get to this point for about 2 months and i think i need some change
Answer:
I change up my abdominal exercises every other day or every two days depending on my training regime. Take a look at some of these and see what works best for you.

You need to increase the amount of crunches that you do every week. Also try adding weight to stomach area while doing sit-ups.
