Wide-Grip Lat Pulldown

Trains the Lats.

How to do it

Set the thigh pad on the machine so your legs are held firmly and your feet reach the floor.
Stand up, take a wide overhand grip on the bar — roughly one and a half times shoulder-width — then sit down with your arms straight overhead.
Lean your torso back about ten to fifteen degrees and hold that angle. Sitting perfectly upright makes the bar hit your face; leaning back forty-five degrees turns the movement into a row.
Draw your shoulder blades down before you pull, letting your shoulders drop away from your ears.
Pull the bar down toward your collarbones by driving your elbows down along your ribs, not by pulling with your hands.
Touch or come close to the upper chest, pause briefly, then let the bar rise under control until your arms are straight and your shoulders rise again at the top.

Pulling the bar behind the neck. It gets the arms further back at the cost of a far less comfortable shoulder position, and gives up more than it gains. Pull to the collarbones in front.
Leaning back further and further as the set goes on. Once the torso is swinging, the load is being moved by momentum and the lats are doing less than a lighter weight would ask of them. Pick an angle and hold it.
Not letting the shoulders rise at the top. Holding the shoulder blades permanently pinned down removes the part of the range where the lat is stretched under load. The shoulder blade is meant to move with the arm.
Grip width doing more work than it deserves. A pulldown to the collarbones with the elbows tracking down along the ribs trains the lat well at any reasonable grip; where the bar finishes matters more than how wide the hands are.
