"Lead from the top down", this quote has been around for years but it wasn't until recent that the public has taken this mantra to heart. Neck and head injuries can result in dire implications. The topic has gained much interest recently due to the increased documentation of debilitating cervical spinal injuries and concussions, particularly in American football. When compared to ankle, knee, or shoulder injuries - although serious, but less life threatening - cervical spine and head trauma go to the top of the list of importance. And it's not just American football as the focal point: soccer, MMA, rugby, auto racing, and other combative and cervical-spine/head compromising activities need to be scrutinized when it comes to these anatomical areas.
Enter many high school or college weight rooms and take an inventory of the equipment: a plethora of benches, squat racks, platforms, dumbbells, barbells, and weight plates abound. How many neck machines do you see? Usually none or maybe one. Ask the strength and conditioning coach, head sport coach, or athletic trainer what the neck and head training protocol is above and beyond their limited or non-existent equipment. Often the answer is nothing, or possibly something posted on a wall or dry-erase board. Whatever the case, it's either not performed, done sporadically, or executed in a perfunctory manner because it's not a priority.
