Stand or straddle a T-bar row machine or landmine setup with a reverse (underhand) grip on the handles. Keep your chest up and core braced. Pull the bar toward your torso by driving your elbows back and squeezing your shoulder blades together. Slowly lower the weight back to the starting position under control and repeat.
