Lateral Dumbbell Raises
Stand with legs just slightly wider than shoulders, dumbbells at your sides and a minor bend in your elbow. Raise the weights at your sides with upper arms going in line of your body. Exhale on the way up, inhale on the way down.
First thing to note about this exercise is that most experts suggest to only lift your upper arms until they make a straight line with your shoulder, parallel to the floor. Doing so focuses on the deltoids, which is obviously the intention of the exercise. You can, however, lift the weight a little higher to isolate your trapezius. It is especially important to watch your form while performing this exercise as it is very easy to get hurt if done incorrectly. This means do not jerk the weight and always control the lift. The only movement should be that of your arm at your shoulder. You can stand with your knees slightly bent to help maintain balance. You can do this exercise sitting down or standing up. Also please note that depending on your body structure, it may be more comfortable to start with dumbbells in front of you, at your sides, or at your back. Pick the starting position you are most comfortable with.
