Leaving aside the discussion about conditioning volume (8 hours/wk is a lot for a non-endurance athlete), the existing data suggests that frequency doesn’t really have a significant effect on health. If anything, I think distribution of training likely has a bigger impact on performance with respect to fatigue management, e.g. spacing out intense or high-priority sessions.
Both templates would be reasonable. To my mind, the 2nd gen bodybuilding templates prioritize muscle size with more isolation and machine work than the hypertrophy programs, which have more barbell-based work. Personal preferences aside, I’d favor the 2nd gen bodybuilding template for this application.
