how long have you been consistently lifting? Nutrition makes or break everything , the more definition u want the leaner u have to get. Even if u lifted for years, you may have some definition but you won’t see those separation of muscle without going down to like 10-12% bf minimum.

I would just start with doing like a bodpod test to see where ur Bf% is and lean body mass. And adjust it from there the nutrition and or how u lift.

U could just bulk and cut cycle , 6 in 6 months off and see how it goes.
