1. Stand with the bar in front of your shoulders, your grip slightly wider than shoulder-width, elbows slightly in front of the barbell.
2. Without using any momentum from your lower body, press the bar straight up over your head. At the top it should be directly over your shoulders and mid-foot. Allow your head to poke through the window created with your arms and the bar
3. Slowly lower the bar back down to the starting position, retracting your head out of the way of the bar
