Quote from achilles28:
So deadlifts are a back exercise? I should drop them from leg day?
Ya, lower back. You should not combine major compound exercises on the same day. For one thing you're sub-optimal due to fatigue on the second compound, and further they're not a primary leg movement.
One 4-split option:
Back/bicep (DLs, rows or pullups), curls
off
Chest/tri (alternating wide and narrow bench), weighted dips
off
Legs (Squats)
off
Abs/shoulders/traps (abs), overheads, rack cleans (3 sets max)
(off) on day 8. Offers a bit more rest
