I've been doing WBB1 now since last june. Strength has gone up, size too. I've gained 20 lbs since August, and kept my BF at 12%. My problem has been on chest/back day, I kill my lower back doing DLs, then when I move on to rows, I can't do BB rows. If I lean forward at all, even the slightest little bit, my back gives out because it's just too wiped from the DLs.. I was doing the BB rows, but I was pretty much upright, bringing the bar from groin level to just above my navel. I have since switched to using DBs, since I can lean on a bench with my off hand and knee, thereby removing my low back from the equation. I've been making strength gains with them (up to 130lb DBs now, I weigh 172), but my lats don't seem to be growing any wider (thicker, yes). I'm doing weighted pullups, but I think my biceps are doing much of the work. Any thoughts?
