Stop hitting your back with countless useless exercises and start working towards a double bodyweight chinup you fucking cuckolds.
Seated rows work your entire back and with a side benefit of working biceps and shoulders as well and is safer and lower overall impact than deadlifts, it's a perfectly legit exercise.
Why even lift if your not gonna make it?
Who said weighted chins had to be the only movement you do you damn kneegrow? Although rows are pretty pointless if you do weighted chins and deadlift, particularly if you do any variation of the olympic lifts at all on top of that.
