Sit on a plate-loaded neck extension machine with your head positioned against the padded lever. Grasp the handles for stability and, keeping your spine neutral, push your head backward by extending your neck against the resistance. Slowly return to the start by flexing the neck forward. Control the motion to avoid jerking and maintain tension on the neck muscles throughout the set. :contentReference[oaicite:1]{index=1}
