How to get bottom packs

I know its not an overnight thing, but I already worked my way up and got my top 4 packs,
Now i'm wondering how I can get the rest of my packs, especially the bottom ones.

I think I have an 8 pack, not sure though.

Ive been doing alot of ab crunches lately, and I dont really see any improvements on the bottom ones.

Help basil?
