Arthur Jones is the legendary founder and developer of Nautilus exercise equipment. He pioneered the concept of high intensity, joint specific strength training and was the first to develop machines dedicated to each area of the body. He proved, through exhaustive research, that it is the most effective way to get results in the shortest period of time. When he evaluated the back extension machine, he found it did not do an adequate job of strengthening the back muscles. In 1972 he began what was to be fourteen years of research and development with the goal of designing the first meaningful tools for testing spinal function, including strength, muscular endurance, and ranges of motion. In 1986, he founded the MedX Corporation and after years of development and testing, validated by independent research teams at the University of Florida, perfected the medical lumbar extension machine. He subsequently developed the cervical extension machine providing the medical community with the first tools capable of producing specific and accurate tests of functional ability, as well as the finest source of rehabilitative exercise. These machines have helped hundreds of thousands of people around the world eliminate their back and neck pain. Arthur Jones devoted his life to educating people about the proper way to exercise and designing equipment best suited to his training methods.
"I've been broke more times than I care to count and I still made the Forbes Fortune list of the 400 richest by the mid-1980s. When I sold Nautilus Sports/Medical Industries in 1986, I owned a large farm located north of Ocala, Florida. The 350 acres of prime real estate housed the largest privately owned airport. including three Boeing 707 airliners and the largest exclusively owned collection of exotic wild animals. My menagerie consisted of 100 African Elephants, 4,000 crocodilians, three albino rhinos and Micky, my 400 pound pet gorilla."

The low back muscles are usually under-developed after a back injury. Even people with no back pain can have a weak back, since those muscles aren't used during normal activity or exercise. The MedX isolates, evaluates, and strengthens the lumbar extensors like no other equipment or exercise can. Using MedX as little as once a week, many people double their lower back strength in just 10 weeks. With JMP and MedX you can say goodbye to back pain for good! Call us today for a free consultation to see if MedX is for you!
Your physical therapist will perform a thorough evaluation on you, including assessing your past medical history, current symptoms, activity limitations, muscle strength, flexibility, joint range of motion, joint mobility and musculoskeletal alignment. They will then work with you on a developing a treatment plan. The goals are to help improve mobility, flexibility, strength, endurance, coordination, balance, participation in daily activities, as well as to decrease pain.
Jones is a white nationalist and Holocaust denier.[3][4][15][10] His 2018 candidate website calls the Holocaust a "racket." He has claimed that the Holocaust was "the biggest, blackest lie in history"[13] and "nothing more than an international extortion racket by the Jews."[9][16] Jones does not support interracial marriage or integration in public schools.[13] In 1993, Jones was filmed in a fight with Milwaukee Alderman Michael McGee Jr. on The Jerry Springer Show.[17]
MedX™ treats and reduces chronic back pain and dysfunction through specific spinal strengthening exercises using the MedX™ Lumbar and Cervical Extension Machines. Pressure on the spinal column causes pressure on nerve roots, which in turn, causes pain. MedX™ focuses on increasing strength, decreasing pressure on spine and nerve roots, ultimately decreasing pain. It also reforms inflexible scar tissue into a more normal functional scar. In simple terms:

Ryan Buchholz is a full-time physical therapist who started at RehabAuthority in June. He is a Doctor of Physical Therapy and received his degree from his hometown at the University of Mary in Bismarck, ND in April of 2016. He decided to pursue PT when he was injured his senior year of track and was brought through rehabilitation by his soccer coach.


Jones often prided himself on being a generalist, something which he describes as a move away from the stubbornness and short-sightedness of 'specialists'. He attributed this in part to his upbringing in a family of physicians, as he found their attitudes toward medicine revolved around what they were taught and nothing else. One of his favorite quotes was Robert A. Heinlein's "specialization is for insects." He often cited that his observations gained from flying allowed him to understand the requirements for developing exercise machines. He believed in the competent man, that "a man should be able to put food on the table, build a house, tan a hide and deliver a baby."[This quote needs a citation]
The MedX lumbar extension machine provides functional testing and rehabilitation of the lumbar spine. A unique method of stabilizing the pelvis, providing true isolation of the deep muscles of the lumbar spine(erector spinae and multifidus). Weakness in these muscle groups has been associated with chronic low back pain and susceptibility to future back injuries, pain and disability.
