Stand with your feet spread just wider than shoulder-width apart. Bend your knees and hips, with your trunk between 45 and 75 degrees in relation to the floor. Lightly hold the dumbbells with your arms pointing straight down. Keep your wrists in neutral and your elbows slightly bent. Keep your shoulder blades back and your head in a neutral position.
Begin pulling your arms up with your elbows pointing straight back and close to the sides of your body. Continue to pull your arms back and up until your upper arms are approximately parallel to the floor. Hold. Maintain a natural arch in your lower back, keeping your arms as relaxed as possible. Slowly return your arms and lats to the starting position, keeping your scapulae retracted and tension in your lats. Repeat.
