Pull yourself up until your chin clears the bar, elbows pointing down.
Slowly lower yourself until your arms are completely straight, letting your shoulders relax.

Full technique — 7 steps

Set the assistance so you can complete reps without kicking or losing your top position.
Kneel on the pad and take an underhand grip on the bar about shoulder width apart.
Start with your arms completely straight overhead, shoulders elevated, and legs stable on the machine.
Tighten your stomach and pull by driving your elbows down toward your sides.
Continue until your chin clearly passes the bar.
Lower under control to full elbow extension, allowing the shoulders to rise at the bottom.
Begin the next rep with your arms completely straight, without bouncing off the assistance pad.
