The cervical spine consists of 7 vertebrae that form the top of the spine, also known as the neck. It holds up the skull and is the most mobile part of the spine, with the ability to rotate side to side, up and down, and in almost every direction. The muscles of the cervical spine control movement of the head and connect with the upper back and shoulders. The muscles in and around the cervical spine can become weak with sustained forward head positions that occur during computer use leading to pain, headaches and limitations in range of motion. It is important to make sure posture and neck strength are not ignored during your exercise routines.
