The dumbbell lateral raise isolates the side (lateral) delts, which are what make the shoulders look wider. Pressing movements barely train them, so direct raises are where most visible shoulder width comes from.
Primary muscles
Pick a couple of dumbbells and stand with a straight torso and the dumbbells by your side at arms length with the palms of the hand facing you. This will be your starting position.
While maintaining the torso in a stationary position (no swinging), lift the dumbbells to your side with a slight bend on the elbow and the hands slightly tilted forward as if pouring water in a glass. Continue to go up until you arms are parallel to the floor. Exhale as you execute this movement and pause for a second at the top.
Lower the dumbbells back down slowly to the starting position as you inhale.
Repeat for the recommended amount of repetitions.
3–5 sets of 12–20 reps with light weights. The side delts recover quickly, so you can train them 2–3 times a week.
