Attach a lat or short straight bar to the machine.
Grab the lat bar with hands at supinated, close-grip and sit down, placing legs underneath the pads of the machine.
Keeping your elbows pointed forward, pull the lat bar down, towards your sternum.
Take a brief pause at the bottom of the movement, then re-extend your arm to the starting position.
Repeat this range of motion until all reps are completed.
