Opinion on ab exercises?

You probably already have strong abs if you are doing that much. If you want them to show you have to focus more on cardio to burn off all the fat. It is no joke you have to really burn alot of fat like below 8% body fat. Running, jump rope that kind of stuff will do it. It might not make sense but it is how you do it. Keep in mind too that it is harder for some people to accomplish this because of genetics.
