Purpose of Exercise: To train the front and side deltoids. This is the meat and potatoes of shoulder exercises. When done from a seated position the movement will be stricter than when standing.
From a sitting or standing position, grasp a barbell with an overhand grip and hold it at shoulder level, palms underneath for support, hand outside your shoulders, elbows tucked in and under. From a position about even with the collarbone, lift the bar straight up overhead until your arms are locked out, being careful to keep the weight balanced and under control. Lower the weight back to the starting position.
