This exercise hits the deltoid muscles located at the top of your shoulders. These muscles are used when you pull the bow back and aim. To do dumbbell lateral raises, you will need two dumbbells. You should stand with your feet shoulder-width apart, holding a dumbbell in each hand. Your palms should be facing your sides. With little to no bend at your elbow, slowly raise the dumbbells up along your sides until they are at your shoulder. Slowly lower them back down and repeat.
