The dumbbell lateral raise is an isolation exercise that targets the shoulder muscles, specifically the lateral deltoid. It involves lifting a pair of dumbbells laterally away from the body while maintaining a slight bend in the elbow. 

The exercise can help improve shoulder strength and stability, enhance posture, and contribute to a well-rounded upper body physique. Variations include performing the exercise while standing, sitting, or lying down, and using different hand positions or weights. 

It is important to maintain proper form and avoid using momentum to perform the exercise effectively and prevent injury.
