The simulator is a universal device designed to relieve the load and fatigue from the muscles of the back and spine, improve flexibility, correct posture, eliminate muscle clamps, and stimulate blood circulation. It will provide not only stretching of the spine but also additional massaging thanks to the massage rollers on the arch. It consists of a solid plastic base with a flexible arch in the middle. The length of the arch corresponds to the average length of the spine and has three height adjustments designed for different fitness levels. The relief allows for acupuncture-like effects on the back muscles without causing discomfort due to the soft nitrile rubber padding. Start exercising on the first level of curvature, then as your back strengthens, move on to the second level. The maximum level is intended for physically fit individuals looking to achieve a stronger stretch. To achieve maximum effect, it is necessary to exercise regularly 1-2 times a day for 5-10 minutes. The maximum weight capacity is 110 kg. Advantages: 3 levels of curvature for different levels of intensity, 2 ways of application: vertically and horizontally, easy to assemble and disassemble, compact when folded, packaged in a cardboard box.
