Not fond of it for someone past a beginner phase in training. And I mean a rank beginner who can benefit from an unchanging routine for all three days per week of full body training with those exercise. If one were to tack on a lateral raise or overhead press, row, ab/core exercises, and a hip-hinge or deadlift variation somewhere in the weekly programming, then it’s fine. But then again that takes away the whole attraction of just doing three exercises per week, whatever the frequency.
I believe lack of rowing, a vertical push or lateral raise, and a hip hinge exercise is a recipe for injury and one clunky looking physique. But like others said, one can do worse.
