Arthur Jones is the legendary founder of Nautilus. In 1986, he founded MedX to perfect the testing of human strength, endurance and range of motion. After years of development and testing, validated by independent research teams at the University of Florida, MedX perfected its medical Lumbar Extension machine. It has since helped tens of thousands of people around the world reduce or eliminate their back pain while increasing their function and quality of life. Subsequent developments produced the MedX Cervical Extension, Rotary Neck and Torso, and Knee/Hamstring machines, providing the medical community with the first tools capable of producing specific and accurate tests of functional ability along with the finest source of rehabilitative exercise.
