Any bent over rowing (including cable rows) motions, BB or DB, affects the lower back very strongly. Even lat pull/chin hit the lower back to a lesser degree. It is quite hard to separate the upper back from the lower part when doing a standard back workout. As far as the program listed by Lugar, too, too many redundant exercise, as The Pumpster suggested. Have not had the opportunity to see any program's listed as 5 5 0 or 120 so am assuming that would be zero rest and than 120 second rest after. If the 2 second up and 6 second down (negative) works well for you, than fine.
OVT is not like GVT. The 5X5 approach is a basic mass/strength program that has been used probable for over 60 years . The original concept was squats, BB rows and bench's in the same three day a week workout. Called the Big Three for good reason. (I pray to God that Lugar is not doing all those back exercises in one workout...yikes!) Progressing up (5 reps) to the highest weight used at the third set, than doing whatever to keep the rep range at 5 for the last two sets. All those programs , like 3X3,5X5, 8X8, 10X10, each have a different theme; BB'ing, strength/power, muscle mass, muscle refinement, etc. But they are all, or should be, the same in that the rep's are meant to be constant. Example; 5X5...5 reps only, 8X8...8 reps only, etc throughout each set.
I'm not a big find of high volume BB'ing sets (tends to be self defeating) for anyone but if Lugar wants to experiment with any extended version of 5X5's than he might consider the following:
DL...Biggest compound exercises are usually done first
BB row...curl grip...elbows in
Chin...Hammer grip...elbows in
5X5 each exercise...once a week for most. Feel free to include chest work in the same day, but your best move would to have a individual day for chest. Like monday-back...wednsday-leg...friday-chest. Throw in a few sets of those sissy arm exercises at the end of a workout if you wish. Good Luck.
