Sit facing the machine and wedge your knees under the restraint pad.
Take a wide overhand grip on the bar, i.e., your hands should be gripping the bar near each end.
1) Inhale and pull the bar down behind your neck, bringing your elbows back as you pull.
2) Exhale as you complete the movement then, begin the next repetition.
Notes:
This exercise is excellent for enhancing back width. It primarily works the lats, specifically the lower part. The exercise also works the forearm flexor muscles, biceps, brachialis and brachiordalis in conjunction with the rhomboid and lower trapezius muscles, which work to press the scapulae together.
This is a great exercise to begin with prior to moving on to chin ups, which require a great deal of foundational strength.
