There is also a special null type, the type of the expression null, which has no name. Because the null type has no name, it is impossible to declare a variable of the null type or to cast to the null type. The null reference is the only possible value of an expression of null type.
The military barbell press mainly works the shoulder, or deltoid, muscles. The anterior deltoid, the front head of the shoulder muscle, does much of the work. The side, or lateral, deltoid and the rear, or posterior, deltoid are also involved in the movement, although to a lesser degree than the anterior deltoid.
The military press is one of the best old school shoulder building exercises and forms the cornerstone of many good shoulder workouts. Set up for the military press by loading the weight you want to use on a barbell. Stand facing the barbell with your feet at around shoulder width apart. Grasp the barbell using a overhand grip (palms facing the floor) with your hands at around shoulder width apart.
