Machine Shoulder (Military) Press
The shoulder press machine primarily works the deltoids, but it also brings the surrounding muscles into play. Working all the shoulder muscles simultaneously helps to prevent injuries caused by muscle imbalances.
- Sitting upright with your abs locked in, grab the bar with both hands. Using a smooth motion, press the bar upward by extending your arms. Pause briefly at the top then lower your arms in the same controlled manner.
- Adjust the seat so the handles are level with your shoulders as you are sitting upright. Be sure to maintain good posture even though you are seated.
