I can do any day, any order BUT I have also had the best success with what EHG said with a 4 day a week training schedule. Generally speaking, I get more rest/ food over the weekend so on Monday I am freshest. I train the squat that day. Wednesday is my bench day because I can bench with sore legs, whereas had I had benched Monday, my back wouldn't allow me to squat to the fullest potential. If I do deads on Monday my upper back is beat to shit so benching on Wednesday is less than stellar. I do 'Best' with Squat,Bench,Dead,Press. Then again, I am nearly 41 so I'm not as 'bulletproof' as I once was Your mileage may vary. Hope this gives you something to think about.
