Spinal disease is usually caused by the deformation of the disc between the vertebrae, but it can also be caused by the problem of the spine itself. As the age of onset is lowered due to the wrong postures and habits, spinal diseases are growing frighteningly among young people. Spinal disease accounts for more than 80% of the population in Korea, and 47% of younger students suffer from spinal diseases, so it is no longer a disease of old age.

On the other hand, in addition to the above-mentioned spinal diseases, there is a tendency to increase the interest in exercise apparatuses that can solve problems due to large and small joints constituting the human body such as arms, shoulders, and leg joints, .
