A rear delt fly done with dumbbells strengthens your upper back muscles and shoulders while working on stabilization strength in your spine, deep abdominals and hips. The exercise requires you to maintain a neutral spine position and avoid moving the torso. Doing a rear delt fly with dumbbells requires you to maintain your posture throughout the movement. Use a lighter weight if you find it difficult to perform the exercise with proper form or use a heavier weight if you can do the exercise with little effort, according to the National Academy of Sports Medicine.

Standing Dumbbell Rear Fly
Stand with your legs about hip-width apart and hold a dumbbell in each hand by your side. Choose a weight that allows you to perform eight to 12 repetitions.
Bend your torso forward and bend your legs slightly so that your arms extend below your body with your hands facing each other as you hold the dumbbells. This is the starting position.
Exhale and raise your arms out to your sides with your hands facing down, squeezing your shoulder blades together during the movement. Do not round your spine or move your head forward.
Inhale and lower your arms to the starting position. This completes one repetition. Perform two to three sets of eight to 12 reps.
