Lol . . . that foreigngirl is one tough customer. LoL
If I were you, I'd remember that squats are the key here and I'd let the rows go for right now, maybe do chins instead or something. Better to rest the lower back for a day or two and get ready for that big squat PR! I just went through that this week, and I'm in week 6 of my run too, so we're kinda' tracking here.
Just something to consider: I’d originally planned on doing the DF version as well, but I’m finding that I can keep some SF progress going here if I make small adjustments on the fly. Maybe you’re not comfortable with that and prefer the hard and fast “plan” but its just something to consider. I feel like I’m going to continue making progress for awhile here just by going a little more intuitively, backing off a lift here, a lift there, dropping/adding volume here/there, and keep the PRs moving without really following the DF plan. You may be able to as well. I really didn’t like having to reramp b/c I lost a bit of strength and feel like taking two steps back isn’t very helpful in the long term. I’d rather pound away for weeks on end, taking little breaks when I feel the fatigue/back aches, etc. and not have to drop down to sissy weights and run back up. I mean, you may find that you can make a few adjustments and get into weeks 7-8 no problem, setting records, and then take a little break, and keep going rather than having to reset or arbitrarily drop into triples in weeks 6 & 7, you know?
