Behind The Neck Press
This exercise can be done either standing or sitting and with either dumbbells or a barbell. Sitting with a barbell is the preferred method though.
Starting position – start seated with the barbell resting on a rack behind your neck, grip the barbell evenly with hands about shoulder width apart.
Movement – lift the weight directly above your head without locking your arms into the straight position. Then lower the weight back down behind your head slowly.
Note – Keep your back straight and flexed.
