Using a bench that can be angled at 45 degrees, lie down while facing up.

Grasp the bar just outside shoulder width apart, ensuring that the hands are evenly distanced from the center. Drive the bar upward and bring the bar to where it is aligned with the upper part of the chest. If someone is viewing you from the side, the elbows should be directly under the hands.

Slowly descend until the bar is 1-3 inches above the breastbone.

Press the dumbbells up in a straight, vertical line until the arms are fully extended. Focus on the chest muscles being the active engine behind allowing you to complete the movement.
