Doing them all is a great idea. However, I have gone for very long periods of time without doing any sort of rowing movement.
In that same time span I did my usual Chin/Pull-up workout. This involved performing no less than 200 to 400 Chin-ups and or Pull-ups per week. It depended on the weeek and if I was working with weight or not.
I Then trained with a Powerlifting friend (he was not training for a contest and he weighed about 180 at the time) who insisted that we do Barbell Rows. After we warmed up with light weight he placed 185lbs. on the bar (Just a tad less than my body weight).
I was able to perform 10 quality repetitions with no problem. He did the same. He then pumped it up to 200lbs. I garnered 8 reps and then 6 on the following set. He proceeded to accomplish the same amount of reps. No question that by the third set he was having an easier time of it than I was, but my reps were still pretty good.
I never forgot that experience.
Keep in mind I have never gone long periods of time performing rows only at the exclusion of Chins. Maybe I would still be strong in the Chin-up department from rowing who knows?
Also, if I were doing rowing in addition to Chins for that long period of time I’m sure I would have been even stronger in the Barbell Rows. (obviously).
I do think that performing Pull-ups and Chin-ups did help my rowing a great deal!
