Behind the Neck Press
This is an Advanced level lift. It's difficult to execute and has a higher risk of injury. You've been warned!
However, this is also a great way to build up all of the muscles around the shoulders. The issue lies in the starting position with the bar on your shoulders.
Your hand placement will be the difference between success and failure. Your hand position needs to be much wider than a regular standing military press and the angle of your elbows needs to allow you to retract your scapula: while pushing up, move your head backwards so that the bar stays over your center of gravity. Not too fast or you'll bump your head!
