Lateral raises work your lateral deltoids, which are found on the outsides of your shoulders. Five pound dumbbells are good to use if you are a beginner or you are doing a warm-up set. Stand with your feet shoulder-width apart and hold the weights at your sides with your palms facing in. While keeping a slight bend in your elbows, raise the weights up to your sides until your arms parallel the floor. Slowly lower and repeat for 10 to 12 reps.
