Assisted Pull-up Machine 

Starting Position 
Follow machine instructions for set up and select desired weight. Grip the handles above your shoulders with palms facing outward. Straighten the arms and place knees on the pad, so that your body is upright and abs are engaged. 

Action 
EXHALE: Bend the elbows to lift your body up until chin is above the height of your hands. 

INHALE: Slowly straighten the elbows to lower to the start position to complete one rep. 

Special Instructions 
Remember that on this "assisted" machine, when the weight you choose is heavier, you’re lifting less of your body weight and the exercise is easier. When the weight you choose is lighter, you’re lifting more of your body weight and the exercise is harder. You can experiment with different grips (such as palms facing inward, hands closer, hands wider, etc). 

Muscles Worked: Shoulders, upper back
