I’m lean enough to have striations and a lot of veins but feels like my six pack still doesn’t pop. I do machine crunches every leg day but could maybe hit obliques more. I also think my genetics are just uneven even if they did pop a bit more. Any advice?

I’m lean enough to have striations and veins but feels like my six pack still doesn’t pop. Last time I got body fat checked it was 12%. I do machine crunches every leg day but could maybe hit obliques more. I also think my genetics are just uneven even if they did pop a bit more. Any advice?
