I neglected rows for some time and wish I hadn't, but actually am glad because its a new fronier of muscle I can still add.
ROWS FOR ME, mean 2 different things, so you might want to see if its true for you as well.
I can bend over almost horizontal and pull up to the lower pecs using primarily TRAPS and rear delts and also really working the forearms (another weak point for me). There is no ARCHING of the back in this form.
OR, I can bend over less than horizontal, ranging from 30-60 degrees, and arch the back and pull to the waist. This is an excellent lat exercise although I prefer to do it with dumbells to increase ROM.
If your forearms are the weakest link when you rep out on chins (overhand) then the first form of rows should keep them strong.
If your lats are the weak point, and or if your talking underhand grip, then the second form should be fine, but it will not build the lower traps like the first.
You might loose some chins anyway as you may pack on 5-7 quick pounds.
At any rate, even if you loose your chinning strength, it should come back quickly.
