Set up an incline bench at a 45-degree angle. Sit on the bench with your chest against the backrest and your feet flat on the ground. Hold a dumbbell in each hand with an underhand grip. Lean forward and let your arms hang straight down, fully extended. Pull the dumbbells up towards your chest, squeezing your shoulder blades together. Pause for a moment at the top, then slowly lower the dumbbells back down to the starting position. Repeat for the desired number of repetitions.
