Joseph Pilates, the creator of the Pilates method and inventor of all Pilates apparatus, originally designed the Neck Stretcher to lengthen and strengthen the neck muscles. Joe Pilates was a boxer and gymnast and felt it was important to strengthen the neck muscles. This apparatus also strengthens the facial muscles and promotes spinal stability against force from the head. The springs used are very strong, so great care should be taken when using the Neck Stretcher. Initiation must come from a strong Powerhouse.
