Execution:
1
Set the pulley to the lowest position and hold the handle with one hand.
2
Hinge forward at the hips, using the other hand for support.
3
Keep the elbow high, pinned to your side, starting at ~90°.
4
Fully extend the arm straight back to the end of the range.
Tip: the cable keeps constant tension — you can't cheat with momentum like you can with a dumbbell.
