The military press, also known as the strict press, was once hailed as the best measure of pure strength in an article in the Journal of
Only a few muscles do the majority of the work in a military press, but most your muscles should be contributing in some way. The military press differs from many exercises because you don't have any support from a bench or machine. It's important to be rigid in your legs and core because that creates a base from which you can press.
How to Do It
The exercise starts with the barbell resting on your shoulders or upper chest. Place your hands slightly wider than shoulder-width apart. You then press the barbell up and slightly back, moving it straight up over your head while keeping your knees completely straight. After your press the barbell up, you slowly lower back down to the starting position.

Muscles Used in the Press
Behind the scenes, many muscles work to make the press happen. The most obvious are the muscles of the shoulder, part of the chest and the triceps. Perhaps not as obvious are the muscles of the core that are keeping you upright while you press.
The primary muscles that you use to press up are the deltoids. There are three parts to the deltoids: anterior (front), medial (middle) and posterior (back). In the military
The triceps are the muscles on the bottom of your arm,
The upper part of your chest is also somewhat active in the overhead press. The pectoralis major, the chest muscle, is split into two parts. The lower portion is more active in something like the bench press but the upper region can help you press something overhead. The upper region is called the clavicular head.

The less obvious muscles active in the overhead press are the core muscles. The barbell is about six feet long and holds weights on either side. If you lean too far in one direction it feels like you are going to tip over. Your obliques have to work very hard to keep you from leaning too far to the left or right.
