Believe me, it's a lot of work. Most people who think they are doing more work than what is required from this routine aren't doing as much as they think, and I mean sets with real intensity, not warm-ups and all that ezy mode stuff.
In the context of a week, for just the main lifts alone (not including accessory work) this is the amount of work being performed relative to intensity:
(TOTAL) Weekly Volume for Each Lift:
Front Squat: 69 total reps with intensity ranging from 80%, 85%, 75%
Romanian Deadlift: 69 total reps with intensity ranging from 80%, 85%, 75%
Flat Barbell Bench: 69 total reps with intensity ranging from 80%, 85%, 75%
Incline Barbell Bench: 69 total reps with intensity ranging from 80%, 85%, 75%
Weighted Chinup: 69 total reps with intensity ranging from 80%, 85%, 75%
Weighted Pullup: 69 total reps with intensity ranging from 80%, 85%, 75%
That's an ass load of work.
