Your core has huge endurance.. mostly made up of slow twitch fibers because its constantly working.. just to stand up your core muscles work.. so you can work them alot and they will recover pretty fast.. thats why people tell you to do them often.. if your using heavy weight and you really blast them they will be sore though. I know after some MMA classes my abs are sore as fu ck when i wake up.
