Dumbbell incline rear lateral raise

Set up an incline bench at a 45-degree angle. Sit on the bench with your chest against the backrest and hold a dumbbell in each hand. Extend your arms straight down with your palms facing each other. Keeping a slight bend in your elbows, raise your arms out to the sides until they are parallel to the ground. Pause for a moment at the top, then slowly lower your arms back down to the starting position. Repeat for the desired number of repetitions.
