Ab workout questions?

normally i do my abs in conjuction with lifting, but i wont be able to lift till wed, i can still workout my abs though, and i dont want to go that long without working them out, cuz(well i need to burn of a lil more fat to see them better)i got some strong abs, but i dont know what i should have directly post workout, like for lifting you have a protien shake and creat an insilin spike and everything, do you need to create an insilin spike for abs? or should just have some normal quick digesting carbs withoiut the insilun spike, protien of corse, im out of whey though
