Position
Stand with your feet about shoulder-width apart, with your knees and hips slightly bent. Hold the dumbbells parallel to your body with your elbows pointing back and slightly bent. Begin with your arms forward and up enough so there is some pull downward on the dumbbells.
Technique
Contract the anterior deltoids. Pull one arm up and slightly out, keeping your hand relaxed and your elbow slightly bent. Pull your arm up and out until it is approximately parallel to the floor. Keep you hand just outside shoulder width. Hold and continue to contract the anterior deltoids. Have your arm relaxed, your elbows pointed down, and your wrist in a neutral position. Slowly lower your arm to its start position while lifting your other arm. Repeat.
