There are several q&a's on here about abs, you should maybe check out this one.
Abdominal muscles "get huge" when the fat around them is removed. The "hugeness" is the contrast, the muscles themselves don't really get much bigger.
Abdominal muscles are primarily made up of type 1 "slow twitch" fibers: the human body has (rightly) designed these muscles to do the same boring job every day, all day, similar to your tongue and heart. It's not designed to exert power, push heavy rocks, or other strength goals: your abs are there to keep your erect, help you breathe (especially as a little kid and when in distress) and protect your organs. All of that is about slow twitch.
You should follow a proper strength training program which will include compound lifts that will require your abdominal muscles to do their stabilizing job with increasing resistance. A proper strength training program will also include accessory exercises, like ab-wheels or incline sit ups. You will not outsmart a good training program.
