If it helps, my routine is pretty simple.
Monday: Heavy Lower
Tuesday: Rep Upper
Wednesday: Light Lower
Thursday: Light Upper
Friday: Rep Lower
Saturday: Heavy Upper
I have 4 days I just rotate through:
A: Squats, SLDL's, High Pulls, laterals/rear delts
B: Flat Bench, CG Bench, BB Rows, curls/extensions
C: Front Squats, Sumo DL, Leg Curls, laterals/rear delts
D: Incline Bench, Wide Grip Bench, Chins, curls/push-ups
Heavy usually just means setting a rep or volume PR with 3s or 5s (or 3x3, 5x3, etc)
Rep usually just means setting a rep or volume PR with 7s or 10s (or 3x10, 5x7, etc)
Light just means I do a variation to make it harder, so High bar, beltless, long pauses, deficit, etc.
I try to work up to some 'heavish' single one the main lift every day, because I felt 85%-100% was just an area where not only my form broke down quick, but I was also 'intimidated' by weight that just felt heavy when I unracked it, so I started doing 'over-warmups', or daily 'minimums' as opposed to a daily max.
This has been working very well for me so far, and is influenced a ton by HeavyTriple, who I lift with IRL now and again and is a good friend.
