The Nautilus Wide Lat Pulldown is a close cousin to the Narrow Lat Pulldown. It allows you a better squeeze at the bottom than other wide lat pulldowns and emphasizes an infrequently worked muslce, the teres major.
Attempting to build your back can be challenging because it has many muscles. The Nautilus wide grip pulldown is a worthy addition to your back arsenal because it addresses both a major muscle, the lats, and one that is rarely worked, the teres major.
The teres major may be a mystery to some readers. This muscle, circled in green on the accompanying diagram, contributes to shoulder stabilization and also internal and external rotation of the shoulder. The teres major also has quite a visual presence within the back, so many bodybuilders try to find ways to emphasize it.
As you can see from the picture of me performing the exercise at the start of this post, body position is quite different than the standard lat pulldown. The extreme forward lean is necessary to provide the correct line of pull to accurately target both muscles. When setting up the machine make sure the seat is low enough so that when your arms are in the fully extended position the weights do not bottom out. When you are ready to begin the exercise grasp the handles and then sit down. Adjust your body so you are leaning forward enough so that when you begin the pull your arms and elbows stay in line with your body. Palms face forward for the duration of the exercise.
As you can see from the video Bud maintains the necessary forward lean throughout his set. He keeps his torso steady and does not rock back and forth as this would be cheating. Also note that when he is at the bottom of the movement his arms are in line with his torso and his palms are facing forward. He demonstrates great execution of the exercise.
As you watch me (Nancy) perform the exercise I maintain relatively good position throughout the set except near the end. At the beginning of the set I maintain the forward lean and I also get a good squeeze throughout the back. Notice near the end of the set how I allow my shoulders to rise up and round a bit as I fatigue.
