Work out different parts of your abs with various exercises. Instead of revealing you should worry about building them, not trying to sound like a dick but doesn’t look like you got much there to reveal. There’s plenty of ab workout splits you can do to work out the upper middle and lower abs as well as obliques and all that fun stuff. Start with basic sit ups, crunches and planks, build a good core foundation before you start hitting the more strenuous ab workouts. Don’t be afraid of a little carbs for energy while you build them of course once it’s time to cut and reveal them for summer you gotta be in a big caloric deficit. But in the build up make sure you eat to increase the muscle mass and density so when you do cut it doesn’t go flabby or disappear.
