Here are a few dumbbell exercises to add some meat to those delts.
Seated Dumbbell Should Press This is the best dumbbell exercise for adding mass to your delts.
Start with sitting on a bench with a straight back with the dumbbells positioned on your knees.
Try to press your back against the bench with your feet flat on the floor.
The tricky part of this lift is actually getting the dumbbells into position, especially if you're pushing big weight.
With the dumbbells on your knees, you're going to basically kick each dumbbell up and into position, which is just above shoulder level, with your elbows out and palms facing forward.
You're then going to press the dumbbells up and in until they nearly touch above your head.
Then slowly lower the dumbbells to the starting position.
You'll find that the more you do these, the better you'll get at hoisting the dumbbells into position.
These can also be done standing up.
Front Dumbbell Raises You begin the lift with a dumbbell in each hand, with your palms facing backward.
Your feet should be about shoulder width apart.
You'll want to make sure that you want to keep your arms straight but not locked.
Lift the dumbbells in front of you in a wide arc until they are slightly higher than shoulder height.
Slowly lower the weight in the same path that you lifted.
Try to limit swinging and momentum as this will take the emphasis off of the shoulders.
This lift can be done with one dumbbell at a time or a barbell as well.
Dumbbell Lateral Raises Begin with the dumbbells in front of your thighs.
Bend over at your hips slightly with your knees bent.
With elbows slightly bent, raise your upper arms to your side until your elbows are shoulder height.
Lower your arms in the same motion.
As with the front dumbbell raise, you'll want to limit momentum so that you can focus on using the shoulder to lift the weight.
A number of variations on the lift exist including doing them seated or one at a time.
With these exercises you should be well on your way to developing those delts.
