Lateral raises are a strength training exercise primarily targeting the deltoid muscles in the shoulders. To perform this exercise, stand upright with a dumbbell in each hand, arms at your sides. Raise your arms out to the sides until they are parallel to the ground, then lower them back down. This movement helps build shoulder strength and improve muscle definition. This exercise can be done with various weights, depending on your fitness level. It's important to maintain proper form to avoid injury, keeping your back straight and avoiding swinging the weights. Lateral raises can be included in a comprehensive upper body workout routine.
