Do shoulder width chins instead of pulldown. way better
all I do is rows on one day, and chins on another session with suported T-Bar rows.
Plus some extra stimulation from power cleans and snatches on my leg day.
if you do pullups/chins/ pulldowns on the same day as rows, you will not be able to put full effort into them I feel.
if you have to do em in the same session chins/pullups are harder, so do em first then do rows.
Some people do deadlifts firstup on back day, but I do these on lower body day.
