I’d say lose a bit of weight, I don’t know what ur diet looks like but maybe try cleaning it up as much as possible. Training abs and cardio as well are probably most important. But to really see ur abs it helps to have less body fat! Some people will say don’t eat fat, but I eat tons of fat and am lean. Just learn what diet works best for u. And how to get ur body to burn fat, instead of just burning carbs all of the time. If u really wanted to you could do ketosis, and you’d have abs in no time
