1. May be performed in a standing or sitting positions. Be sure that if you are seated your back is straight; if standing your knees are slightly bent to protect your lower back.
2. In a seated position; grasp a dumbbell in each hand. Keep the dumbbells at hanging straight down at your sides.
3. Simultaneously, raise the dumbbells directly to your sides. Be sure to turn your palm facing down, and have your elbows slightly bent. Once your hand, elbow and shoulder form a parallel line, pause and hold for a second.
4. Next, lower the dumbbells to your sides.

This is an excellent movement for isolating the side deltoids. Once again, DO NOT swing the weight up, carefully muscle it up! While performing this exercise, be sure NOT TO turn your thumbs down at the top of the movement. This is an un-natural positoin for your shoulders to be in and leads to injury in the rotator cuff region. Remember, since your elbows are slightly bent, you will be bringing the weights slightly forward. Good Luck!
