Neck isometrics work the neck muscles against hand resistance without moving the head.
Muscle group: Back
Steps
Sit or stand upright with your head neutral and eyes forward. Place both hands on your forehead. Gently press your forehead into your stationary hands so the neck muscles contract without head movement. For the backward direction, place your hands behind your head at the level of the tops of your ears and gently press into them while keeping your head still.
