A common problem among many individuals working at desks or in front of computers is neck pain. This is caused by a constant forward head lean which stresses the neck muscles. To help improve this posture, here is an exercise that you can perform to help improve your head posture. Step 1: Lie on a box or any surface that has a ledge. Position yourself so your shoulders are supported but your head and neck are not. Step 2: Using your hand, push your head backwards and make a double chin. The goal in this position is to make the head in line with the box. This creates a straight posture from the head down to the back. Hold this position for 5 seconds. Step 3: Gently release your head and relax it back.
