The classic 'V' shape that is such a desirable trait to any bodybuilder is largely responsible to a well developed shoulder girdle that can add so much to someones physical stature. Shoulder width is , to a great extent, determined by skeletal structure, that is something you are born with. But with proper side deltoid development, anyone can create a wide shoulder look.
The deltoids are extremely versatile, and for a complete range of movement, they have three distinct lobes of muscle called heads: the anterior (front), the medial (side) and the posterior (rear) head. There are two basic kinds of exercises for the shoulders - straight arm raises and presses. An ideal shoulder workout should include several variations of these basic exercises targeted to each specific area of the deltoids for all-round development. And of course, the Trapezius muscles tie the neck, deltoid and latissimus muscles together.
In fact, because there are so many different combinations of exercises targeting the different heads of the deltoids, my only problem when constructing my shoulder routine is that I just want to include too many exercises! Anything over 25 sets seems to be excessive, and yet I feel this routine truely pushes my limits and forces my muscles to grow. The best thing is to periodically swap out old exercises for new ones, never allowing your body to grow accustom to any one type of movement.
1. Behind the Neck Barbell Press (4 sets @ 6 reps)
The purpose of this exercise is to train the front and side deltoids, and is an excellent mass builder. Any pressing movement involves the triceps as well. I would definitely start with this exercise as it is by far the most demanding in your routine. Can be performed in either a sitting or standing position, although I personally prefer standing as I feel I can lock out my spine better to avoid unnecessary strain, although the movement will be stricter when seated. As in all pressing movements, keep your forearms perpendicular to the floor (vertical) to transmit the pressing force with the most efficiency and avoid undue strain. Press the weight straight up and lower it again, keeping it under control and your elbows tucked as far back as possible during the movement.
2. Dumbbell Presses (4 sets @ 12 reps)
To train the front and side deltoids. This exercise may seem to be similar to barbell presses of various kind, but there are important differences, the most significant being the greater range of motion you get when using dumbbells. You will also be forced to incorporate ancillary muscles to stabilise the weight during the movement, and train both deltoids independently. Also, because you have just finished a heavy pressing movement, the deltoids are now pre-exhausted to a degree, and you will be able to use a relatively lighter weight than normal to achieve a similar exertion. Keep your elbows out and palms facing forward.
3. Heavy Dumbbell Shrugs (4 sets @ 12 reps)
To develop the trapezius muscles. This exercise can be done extremely heavy to thicken the traps, which will really help create a visually impressive back. I prefer using dumbbells to barbells because I feel I can achieve a better range of motion, forcing my shoulders back to really make my traps work hard. Also works the forearms as a secondary effect. I would highly recommend using lifting straps on this exercise, weight-lifting 'purists' be damned. The purpose is to train your traps, not your grip strength. It's very frustrating to be limited on an exercise due to a loss in grip strength, not fatigue in the targeted muscle area. When performing the shrugging movement, raise your shoulders as high as you can and hold for a moment. Try not to move anything but your shoulders.4. Standing Bent-Over Dumbbell Laterals (4sets @ 12 reps)
To develop the rear deltoids. Rear deltoid are a weak point in the majority of people, including myself, so before my shoulders get overly fatigued, I like to throw in a strict dumbbell movement to target them hard. Stand with a dumbbell in each hand. Bend forward from the waist 45 degrees or more, letting the dumbbells hang at arms length below you, palms facing each other. Without raising your body, lift the weights to either side of your head, turning your wrists so that the thumb ends up lower than the little finger. (Don't allow your arms to drift back behind your shoulders - you're targeting the rear deltoids, not your back muscles).
5. Arnold Presses (4 sets @ 12 reps)
It would be a sin not to incorporate the favourite deltoid exercise of The Man Himself. The purpose of this exercise is to develop the front and side heads of the deltoids. "This is the very best deltoid exercise I know, and I always include it in my shoulder routine" says Arnold. By using dumbbells in this motion - lowering them well down in front - you get a tremendous range in motion. Start in a standing position, elbows at sides, grasp a dumbbell in each hand and raise the weights to your shoulders, palms turned towards you. In one smooth motion, press the weights up overhead, rotating your hands simultaneously to have palms facing forward at the top of the movement. Don't lock out your elbows at the top to maintain the strain on the deltoids, and reverse the motion, lowering and rotating the weight back to the starting position.6. Standing Dumbbell Lateral Raises (4 sets @ 10 reps)
To develop the outside head of the deltoid, with secondary benefit to the front and rear heads. Take a dumbbell in each hand, bend forward slightly, and bring the weights together in front of you at arms length. Start each repetition from a dead stop to stop yourself from swinging the weight up. Lift the weights up and out to either side, turning your wrists slightly so that the rear of the dumbbell is higher than the front. Lift the weights to a point slightly higher than your shoulders, then lower them slowly. Avoid rocking back and forth to cheat the weight up. Can be performed seated for a stricter movement.
7. Seated One-Arm Cross Cable Laterals (4 sets @ 12 reps)
To develop the rear deltoids by isolating and flexing the rear deltoid when reaching the top position of the movement. Sitting on a stool or low bench, take hold of a handle attached to a floor-level pulley in such a way that your arm is fully extended across the front of your body. Keeping your body as still as possible, pull the handle across and up until your arm is fully extended to the side at about shoulder height. At the top of the movement, flex your rear deltoid to get a really full contraction. Return to the starting position, finish your repetitions, then repeat with your other arm.
8. One-Arm Side Cable Laterals (4 sets @ 15 reps)
By now, you should pretty much have nothing left in the tank, but there's always room for a final cable movement to really burn out the shoulders. Side cable laterals focus the work on the side delt head. This movement, which was a favourite of Sergio Oliva's, helps bring out definition in the shoulders and works the rear and front heads as well. You won't need to use much weight at all in the strict movement - 5-8kg should be plenty. Stand upright, with your arm down by your side holding on to a handle attached to a floor level pulley. Place your other hand on your hip. Keeping your arm straight, lift it up in an arc in one smooth motion until it is higher than your head. Lower your arm back to your thigh. Finish your repetitions, then repeat with your other arm.
