The U.S. inventor and entrepreneur Arthur Jones developed the Nautilus range of exercise machines in the 1970s. These machines incorporated the theory of isolating and strengthening muscles without recruiting nearby and weaker muscles. The Nautilus Company became a market leader in the fitness industry. Jones sold Nautilus and founded MedX in 1986. Jones’s aim was to perfect the testing of human strength, endurance and range of movement.
After years of testing, validated by research teams at the University of Florida, MedX perfected the medical Lumbar Extension Machine which isolated, tested and trained the lower back extensors.
Jones spent years researching low back pain and the benefits of strength training for the lumbar spine. In addition to medical back machine, Jones developed a range of machines to exercise muscles of the rest of the body.
