One of the easiest ways to strengthen anterior neck muscles is by simply using your own hands as a form of active resistance. Stand with your feet about hip-width apart and your spine tall. If you are more comfortable while sitting, make sure your feet are flat on the floor and your spine straight. Place the base of your hands on your forehead, just above your brow and begin to breathe deeply. On an exhale, push your head forward into your hands, but don't allow your head to move. Hold the resistance for 3 to 5 deep breaths and then gently relax. Repeat the neck strengthening exercise 5 to 20 times, depending on your comfort level.
