leg day after a deadlift back day

[Zach Trowbridge]

agreed, but NEVER 2 reps on deads and squats if you want to do this sport longer than 2 years.

4-6 reps are perfectly fine for building strength, there's no need for 2 or 3 reps, only if you are a powerlifter.
For building muscle, it's plain useless and will only result in some serious injuries.

I disagree, but anyway, the point is still the same.  If you do squats and deadlifts both for lower reps, they can be done on the same day safely.

The point is: they arent safe at 2 reps. You cant tell me you max out on squats and then move on to max out on deads for the next exercise. Maybe if you do one set with 10 min break inbetween.

I've done (and still do) max box squats and then 3-5 rep sets of RDL's, rack pulls, or deadlifts off a 4" box.  My workout isn't a traditional bodybuilding workout, but I do do them the same day.
