I doubt it. I also suspect they may lead to underwhelming results.
Just a couple of suggestions:
Train four days a week. Use one day to address weaknesses. The other three work on big movements.
You can tack on a few sets of weakest parts each day
You don’t need a core day. Just do some core at the end of sessions.
Just as an example, assuming you’re training Monday, Tuesday, Thursday, Friday:
Monday:
Legs - squat variation, two legs assistance exercises, calves between sets
Shoulders/rows - alternating sets, one exercise each
Core - one exercise
Tuesday
Chest - main chest movement, two chest assistance exercises
Back - two rowing exercises
Arms - one exercise
Thursday
Back - deadlift variation, two back assistance exercises, calves between sets
Chest, shoulders - one exercise each
Core - one exercise
Friday weakness day
Four exercises, focusing on main two weaknesses
