Position
Stand in a ready position with your feet about shoulder-width apart and your knees and hips slightly bent. Hold the dumbbells parallel to your body, shoulders and wrists in neutral, with your elbows pointing back and slightly bent. Begin with your arms forward and up enough so that there is some degree of gravitational pull on the dumbbells providing a resistance.

Technique
Contract your anterior deltoids. Begin pulling your arms up and slightly out, keeping your hands relaxed and your elbows slightly out. Pull your arms up and out until they are approximately parallel to the floor. Keep your hands in neutral and just outside shoulder width. Hold and continue to contract your anterior deltoids. Have your arms relaxed, your elbows pointed down, and your wrists in a neutral position. Slowly lower your arms back to their original start position. Repeat.
