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 primary muscles used in your bench press workouts are the pectorals (chest) and triceps (back of the upper arm). Bench presses and similar lifts, such as incline or decline presses, call on the pectorals and triceps to work in unison, driving the weight upward from your chest. Because the pectorals are stronger and call on the triceps during presses, itâs important to work the press lifts first and isolate the arms after.
