The deltoid muscle is located on the outer aspect of the shoulder and is recognized by its triangular shape. The deltoid muscle was named after the Greek letter Delta due to the similar shape they both share. The deltoid muscle is constructed with three main sets of fibers: anterior, middle, and posterior.
When performing the shoulder press, the deltoids are the prime movers. Three individual muscles make up the deltoids divided by location: anterior -- or front; middle; and lateral -- or back. When you fully extend your arms, you mainly activate your anterior deltoid but still use the whole muscle.he triceps muscle is found on the rear of your upper arm; its main function is to straighten your arm. Your triceps are secondary muscles, which cause your arm to extend during the shoulder press. You use them more heavily in the downward phase to help you slowly lower the weight safely rather than dropping it.
