MedX Research
MedX medical lumbar and cervical spine extension machines and their protocols are some of the most extensively studied in exercise science. With over 70 published studies, the results of these methods are well documented: http://medxonline.net/research-articles/
The Lumbar Spine and the Problem with its Muscles
Because of the way the body is structured, the nervous system will use the hips rather than the lumbar muscles almost exclusively. Consequently, the muscles of the lumbar spine are almost never properly activated. Even without injury, the vast majority of people's lumbar muscles exist in a state of chronic disuse atrophy. In the case of injury, the muscles shut down even further. The MedX lumbar spine extension machine addresses this problem by isolating the spine without the hips, forcing the nervous system to recruit and activate muscles that are rarely trained. The result is rapid and dramatic increases in strength.
