In a standing position facing the barbell, assume an athletic stance.Make sure your core and pelvis are stable and your back is flat. Squeeze hard to maintain this posture.Start the bar at the front of your shoulder, not too close to midline, since that would limit your range of motion and the movement of your shoulder blade as you press.Drive the bar up in a controlled manor to maintain core stability. Also, be sure to incorporate smooth movements of the shoulder blade rotating up and around your rib cage on the back side.Control the bar back down to the starting position while maintaining tension throughout the shoulder.Once all these points are mastered, the last detail to incorporate is a slight forward lean as you press the bar overhead.
