So the back saver is used
The back saver consists of a total of five parts that you can combine with each other: three different height bases and two different attachments (2D attachment for two-dimensional spine correction and 360° attachment for stretching in all directions).
Thanks to the different combination possibilities of all individual parts, you can easily change the height of the back saver. The higher the aid, the more intense the stretch. For the beginning, simply lay on one of the two attachments. With time, you slowly touch to your ideal training level.
The back saver can be used on both the upper and lower back and effectively combat pain. On the upper back, practising with the back saver also supports the reformation of hunchback, on the lower back, the stretch also leads to the normalisation of a strong lumbar (hollow cross).
