Head Rotation
To perform a head rotation, sit or stand with your head facing forward. Turn your head slowly to the left as far as you can manage. Keep the movement of your head smooth and controlled. Do not strain your neck. Once you've turned your head as far left as possible, hold the position for a count of two, then slowly return to the starting position. Repeat the exercise, turning your head to the right, then returning to the starting position. Complete five to 10 repetitions and repeat the exercise three times per day. This exercise releases tension in addition to developing strong neck muscles that hold the chin in place, according to the University of Maryland Department of Environmental Safety.
