The whole-body 3 times a week (or whole-body 3 times a week plus a “gap” workout where you focus on your weaknesses) is ideal for those who need to focus either on technical improvements or neurological adaptations.
A lift-specific approach, where you hit one main lift then assistance work for that lift or the key muscles involved, is super simple to program and works well with almost any goal. It’s especially good for a powerlifter who has mastered technique already.
The modified push/pull split is a great option for “bros” who want to look jacked but hate leg days. By putting quads on the “push workouts” along with pecs, delts, and triceps; and hamstrings on “pull days” with upper back, lats, and biceps, it’s mentally easier and more motivating.
