Start standing with your feet hip-width apart, holding a dumbbell in each hand with a neutral grip (your palms should be facing in toward your thighs) and your arms extended. This is your starting position.
On an exhale, create a slight bend in your elbows, and begin to raise your arms upwards and outwards to shoulder height. Your arms should be nearly straight. As your arms reach shoulder height, begin to bring the dumbbells directly in front of your chest, keeping your shoulder blades down and back.
Next, draw the dumbbells backwards until they are in line with your shoulders.
On an inhale, slowly lower the dumbbells down toward your sides, returning to the starting position. This counts as one rep.
