The lateral raise exercise works the middle portion of your shoulder muscle. Stand with your feet hip-width apart and hold a dumbbell in each hand at your sides.

Bring your arms back to your sides in a controlled motion to finish one rep.
The shoulder flexion exercise will strengthen the front of your shoulder. You can use two dumbbells or a barbell. Hold your arms in front of you straight with your palms facing down.

Bring your arms down straight to your legs to finish the exercise.

Extend your arms straight behind you. Bend your arms back only to a right angle to finish the rep.
