Wide split stance, one cable, max stretch and squeeze per side.
Let your shoulder reach forward at the bottom for a full stretch, then pull to your hip.
The wide split stance and low pulley let you reach so far forward at the bottom that your lat gets a stretch a normal cable row never touches, shoulder rolling forward and all. From that lengthened position, driving the elbow to your ribs gives the back a huge arc of work per rep, with the biceps assisting the pull. One side at a time means every rep gets your full attention and neither lat can hide.
The reach. The split stance and forward shoulder reach at the bottom put the lat under a much deeper stretch before each pull, so the range of motion is longer and the stretch-to-squeeze contrast is bigger than a standard seated or standing cable row.
A little natural movement as your shoulder reaches forward is part of the exercise, but the pull itself should come from the lat driving the elbow back, not your torso whipping open. If you are twisting hard to move the weight, drop the stack.
Light enough to reach a full stretch at the bottom and a hard squeeze at your hip on every rep. This is a stretch-and-squeeze movement, not a load contest, so pick a weight that lets the full range survive the whole set.
