I do these two excercises (on the same day)
(I mostly do underhand for back rows)
The trouble is I hurt my back, or maybe my hip, last September and doing these excercises is bringing back the pain and making walking difficult.
I have tried the versions where you do them lying down but it makes breathing difficult.
Rest untill your ready to start again, and don't do it underhand.
If I were you, I'd just stick with bent-over rows, they get pretty much everything, unless your trying to isolate just one certain muscle.
trying doing bentover row using a sumo stance. it'll allow you to use more weight and lessen stress on lower back. As for rear delt rows i guess you can try reversed flyes. what else are you doing for back?
