Reverse dumbbell flyes strengthen the posterior shoulder and upper back. Strength and development in the rear shoulders and thoracic spinal muscles improve upper body posture, function, and movement.

Hold a dumbbell in each hand with palms facing your body, and your knees slightly bent. Keeping your back flat, bend forward at the hip joint.

Exhale and slowly raise the dumbbells up, forward and out to the sides until your arms are almost level with the shoulders, maintaining a slight bend in the elbows and squeezing your shoulder blades together.

Inhale and slowly lower the dumbbells back to your starting position. Repeat.
