Set an incline bench to a 45-degree angle and sit on it with a dumbbell in each hand, palms facing inwards. Lean forward slightly and let your arms hang straight down, keeping a slight bend in your elbows. Raise your arms out to the sides and up in a Y shape 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.
