All you'll need for this exercise is a barbell and a Landmine or ground base attachment for one end (or just wedge the bar into a corner against a towel).
Load plates on one end of the bar and perform single-arm rows. The angle creates a slightly different movement than a traditional dumbbell row. The value is found in the stretch at the bottom, so use 10 or 25 pound plates to get the greatest range of motion.
Contraction is important too, so I like adding a band to the bar to facilitate a more intense peak contraction as you drive your elbow up and back.
