What are the proper techniques for performing a barbell overhead press to maximize strength and muscle development?

To maximize strength and muscle development during a barbell overhead press, focus on maintaining proper form by keeping your core engaged, elbows slightly in front of the bar, and pressing the bar directly overhead in a controlled manner. Additionally, ensure a full range of motion by lowering the bar to chin level before pressing it back up. Gradually increase the weight and incorporate variations like seated or standing presses to challenge different muscle groups.
