Disclosed is a neck therapy exercise apparatus, comprising a helmet having a weighted flexible rod which may be either permanently or detachably affixed to the top exterior center of the helmet. The flexible rod consists of a first end which may have a connector enabling the attachment of various sized weights to the first end, and a second end, affixed to the helmet. The helmet is custom-sized to a user's head and securely fastened to the head. Therapeutic exercise is accomplished by the user, while wearing the helmet, and weighted flexible rod, slowly rotating his/her head 360 degrees in a generally horizontal plane in either a clockwise or counter-clockwise direction. In different embodiments, the user may replace the weights at the end of flexible rod with increasingly heavier weights as strength is gained during the exercises.
