Performing the: A Step-by-Step Tutorial Dumbbell Rear Fly
Lean forward from your hips until your torso is almost parallel to the floor, let your arms hang straight down from your shoulders, palms facing each other.
Keep a slight bend in your elbows as you raise the weights out to the sides, squeezing your shoulder blades together until your arms are parallel to the floor.
Hold this position for a moment to maximize the contraction in your upper back and rear shoulders.
Lower the dumbbells back to the starting position with control, completing one rep.
