Place your hand at the back of the neck. Meet your neck. This particular body part has a very important job to do — support your head. 

The muscles of the neck flex and rotate the neck forwards and backwards and side to side. While you turn the head, your neck muscles do all the work to carry your head.  As you perform your routines and your neck is not prepared or exercised correctly, the movement of your neck develops into achy and stiff. A well-exercised neck may perhaps save your life and keep you bodybuilding well in to your golden years.

There are four muscles of the neck that keep your head on straight. The rotators muscles supports the head in moving from side to side as well as help you glance over your shoulder while your drive your car. The flexors muscles help the head move up and down, so the chin can touch the chest. The lateral flexors muscles help the head tilt from side to side from ear to shoulder. The extensors muscles support the head, so it can tilt backward and help you see the white puffy clouds in the beautiful sky as a bird flies through.
