A row isn’t always a row
The positioning of the elbow and the path that it takes in relation to the body can dramatically change the part of the back being emphasized.
This is important to know because one, your lack of development in one area or your over development in another part of your back could prove to be helpful or hurtful to how you are performing your movements and two, if you care about how your body is shaped and proportioned, training smartly to put the muscle in the right places and not in others makes a world of difference.
Not always but generally when you keep the elbow tight to the side like how Howorth is positioned in the image you will be targeting the lat with some teres involvement. But if you were to bring the elbow out to the side more, away from the body, you’ll get the teres and mid upper back like the rhomboids and traps.
I love performing my rows how Steve Reeves performed them regardless if I am targeting the lats or the teres and that is leaning forward, keeping the torso down and not raising it as I row toward the body. It is best to use a variety of angles, grips, planes of motion when working any muscle and the back is no different. For a classic development, train classic and use variety.
