yea sorry i disagree, i would never use a routine like this
to simple, small variation,
heavily emphasises the rear delts and lats,
neglects the inner rhomboids heavily, trapsezius, and biceps (yes they are important when hitting your back)
barbell rows are great, but arent a magical muscle builder for the back IMO,
ive never done a barbell row in my life and have an outstanding back, (dont mean to sound cocky but i do)
u also could never lift asmuch weight with a barbell row as you could a t bar row, so ders something to consider
pull ups a great but again to simple for hitting lats, and doesnt give complete overall development of the lats muscle
just my opinion
