The "Motion Navi" allows you to do step & stretch exercises while seated. You can perform exercises equivalent to walking, such as "stepping" and "side-to-side opening," all while seated. It puts no strain on your knees or lower back, so it can be used safely by the elderly. Furthermore, by fixing the step part, it quickly transforms into a "stretch board." You can thoroughly stretch the often stiff "calves" and "hamstring muscles." The footplate has protrusions to stimulate the foot's pressure points. The elderly can safely exercise indoors, similar to walking.
