Purpose of Exercise:To train the front and side deltoids. Any pressing movement involves the triceps as well.
You can do these pressed standing or seated. Sitting makes the movement stricter. Either lift the barbell overhead and set it down on your shoulders behind your head or lift it off the rack of a seated press bench. Press the weight straight up and then lower it again, keeping it under control and your elbows as far back as possible during the movement.
Note: Most physical Therapist today do not recommend this exercise because of shoulder stress on the rotator cuff. Use caution in doing this exercises.
