birdlegs,
be super cautious using that current split. You are training 4 days in a row, which is incredibly draining on the system.
The problem is if you deadlift on day 2, you will fatigue the erectors for leg day. You will not be able to squat at 100 percent.
Personally, I would rework this and find a way to split up 4 days a week.
If you are interested, look at my Fall 2003 program. . it might give you some ideas.
I shall bump the thread for you.
