This exercise is almost identical to one given as a variant to the Cable Side Lateral, but in this case, the exercise can be changed slightly to incorporate either more or less work for the upper back by using varying ranges of motion.
STEP 1. Stand with your feet a shoulder-width apart, keeping your back straight and arms slightly in front of your torso. With your elbows slightly bent, take a dumbbell in each hand.
STEP 2. Raise the dumbbells out and up to the level of your shoulders. Keep your palms facing the ground.
STEP 3. Keeping your elbows bent, lower slowly back to the start position and repeat for the desired number of reps.
