ABSTRACT:
A relatively light, compact and variable neck exerciser which is worn and automatically functions throughout the entire range of neck motion as a result of natural effort an individual performs in his or her particular activity; and simultaneously acts as a neck exerciser and neck protector through the entire range of neck motion during this activity, thereby, being a neck rehabilitator. The device includes a looped spring element fastened, in the case of a football player, between the back of the player's helmet at the apex of the looped spring and the back of the player's shoulder pads at the legs of the looped spring. The spring includes compression, torsion and extention spring sections.
