Looks fairly solid to me. One question: why the dumbbell row and not a straight Barbell Row?
Probably to save his lower back
Yup, since I already tend to fry my lower back with both squats and deads, I prefer to do my rows with dumbbells, lying down on a bench.
Kroc Rows, which seem to be one of the most hard-core exercises I've seen, uses dumbbells (BIG dumbbells!).
