Powerlifting and bodybuilding.
Want to gain muscle definition? You’ll be pumping your body to failure on most reps, or “faking failure” with HRT training.
Periodization will be your friend too. Splitting workouts into the generic “chest day/ leg day/ back day/ shoulder day” doesnt work in fitness, but if you want definition thats the best way to go. It allows you to really push one area while giving the other areas adequate time to recover.
