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 bench press gives us the best way to work all of the upper body pushing muscles. The bench press focuses on the chest, the front half of the shoulder, and the back of the arms. These areas include the major muscles of the sternal and clavicular portions of the pectoralis major, anterior deltoid, and triceps brachii.
