Difficulty: Moderately Easy
Step1
Adjust the bar to the height just above the level of your shoulders. This will be the end point of the downward motion of the exercise. It is important to also adjust the bar stops on the machine so that the bar cannot descend below the shoulder by more than about six inches in case your muscles reach fatigue and you drop the bar.
Step2
Load the bar with the amount of weight you desire to lift. When loading the weight, be sure to use end stops to keep the weight from slipping off during the lift.
Step3
Position your body under the bar. You may have to sit if your height prevents you from standing under the bar and executing an over the head lift of the bar. If sitting, sit just behind the bar to allow you to maintain good posture and lift the bar over your head to full arm extension.
Step4
Lift the bar off the stops and unhook the bar so that it moves freely up and down. Lower the bar to a point that is level with your shoulders.
Step5
Press up with your arms to raise the bar above your head to the full extension point of your arms. It is important to not lock your arms and have a smooth fluid motion. Once you reach the full extension point, lower the bar back to the resting position level with your shoulders. When finished with your set of lifts re-hook the bar on the stops and clear your weights to the storage rack.
