The cable row can be found in almost every (split) schedule. It is an exercise to train the latissimus dorsi, teres major, rhomboideus, trapezius, rear part of the shoulders, biceps and back extensors. A whole mountain of active muscles! The standard version of the cable row starts with the arms extended and the back in a neutral position. You may even feel some stretch on the back side. From here, the handle is moved towards the body, ending with the handle in line with the cable. In the last part of your movement, you're really going to be looking for that extra muscle tension. So make sure the shoulder blades are moving towards each other in the end of the pulling motion. If you want to put a little more emphasis on the mid-back instead of the latissimus dorsi, you can choose to perform the rowing motion with the arms horizontal. Ruben, there is no consensus on how the lats should be countered in the endrange.
