Great, broad shoulders are an integral part of any proportioned physique and big, shaped deltoid muscle* appear highly impressive. Naturally it would be nice to have them Rühl-size, but any well developed delts can set off a build nicely. The musculus deltoideus* are made up of the front, side, and rear heads. For total deltoid development you need to do some precise training for each head and the workout below, if trained with intensity, will ensure maximal stimulant.

A good place to begin any shoulder workout is with a pressing movement. Seated overhead barbell or smith machine presses to the front of the neck are a real power movement. Start with 2-3 light sets to gorge the delts with blood and check you are fully warmed-up, and and then do two heavy sets of 6-10 reps (failure).

Side laterals will work the medial (side) head of the delt and 2-3 sets is all you need. Grab a dumbbell in each hand (enough weight to do 8-10 reps) and stand with your feet shoulder width apart. Hold the dumbbells to the sides of your legs with the palms of your hands facing each other. Keeping a slight bend in your elbows raise the dumbbells out to the sides and upwards in a semicircular arc until they are just above shoulder level. Hold this position for a second to maximize the peak contraction in the deltoids. Lower the dumbbells back to the starting position. Repeat 8-10 times.

Bent over seated lateral raisers are done by sitting on the front of a bench bent over. Hold a dumbbell in each hand and behind the lower leg. Raise them upwards, squeezing at the top, and lower. Do 8-10 reps to work the posterior (rear) head of the deltoid. 2-3 sets is plenty.

Delt training is quick, but, if you've trained with the intensity I intend, then your delts will be burning and worked, and you can always move onto trap training afterwards. A summary of the deltoid workout is:

Seated barbell / Smith press:
2-3 x warm up
2 x heavy for 6-10 reps

Side lateral raisers:
2-3 x 8-10 reps

Bent over seated lateral raisers:
2-3 x 8-10 reps
