More so over the week.
Mainly, doing squats, deadlifts and bent over rows in the same day is too much, especially if you want to lift heavy. Mainly because doing the deadlifts puts stress on your lower back as well as your hammies. Bent over rows also put stress on your lower back, and to a lesser extent squats. These exercises have different primary muscles they target, but the secondaries get worked almost as hard. I've found if you do bent over rows AND deadlifts, one of these exercises suffers as a result because the strain on the back is a little too much to execute them to full potential. So alternating them between days gives you a bit more energy to hit these exercises well when you get to them. You really want to be able to complete each exercise really well, and have enough recovery between exercise days.
You'd get a bit of a different exercise, but because they're big compounds they're still pushing you pretty damn hard. The best way to do a two routine split is to make an alternating A and B routine, both full body but using some different exercises. A lot of people do this and a lot of full body workouts do this. There's many variations too but the simplest is to do it like this (again, like 5x5)
Week 1:
Monday: A routine
Tuesday: rest/cardio
Wednesday: B routine
Thursday: rest/cardio
Friday: A routine
Saturday rest/cardio
Sunday: rest/cardio
Week 2:
Monday: B routine
Tuesday: rest/cardio
Wednesday: A routine
Thursday: rest/cardio
Friday: B routine
Saturday rest/cardio
Sunday: rest/cardio
So you see, over two weeks you do each routine three times, alternating each time. Also, make sure you have at least one complete rest day, no cardio or anything else. Your body needs it.
If you want to hit your hammies on a day you're not doing deadlifts, doing something like machine leg curls would be good, as it's an isolation exercise. I'd do these after your compounds. Same if you want to do your middle back on days you don't do your bent over rows, do machine rows or single arm rows as they don't work your lower back and leg muscles like deadlifts will.
Does it make sense? And if Zimmer or someone wants to correct anything, I'd appreciate it.
