This exercise is an effective neck exercise designed to develop and strengthen the muscles at the back of your neck. Thanks to its strong neck muscles, it makes the neck much more versatile, increasing the range of motion, relaxing the neck and making it strong against injuries.
When the head and shoulders drift forward due to poor posture, some muscles in the chest and neck can shorten and become tight over time, which can perpetuate the poor posture that is causing neck pain. The neck strengthening exercises can help loosen postural muscles and may reduce neck pain.
