Adjust the seat height so that you can sit down and place your elbows against the padding, in line with the rotation axis of the machine. Your glutes should be against the back of the seat. Grab the handles and start with your arms bent at approximately 45 degrees and elbows parallel from one another.
Extend your arms slowly until they are almost full extended, briefly pause, then return to just before the starting position so the weights don't clash. Keep your wrists aligned with your forearms throughout the movement. Repeat for the desired amount of repetitions.
Avoid losing contact between your triceps and the padding during the movement.
