Dumbbell Lying Rear Lateral Raise
Start by lying face down on a flat bench with a dumbbell in each hand. Your palms should face each other. Begin by positioning the dumbbells slightly above the ground, and your arms fully extended but slightly bent at the elbows. From this position, lift both weights out to the sides in a semi-circular arched movement while breathing out. Continue this upward movement until your arms are parallel to the floor. Lower the dumbbells back down to the starting position as you inhale.
