Manufacturer's Description -------------------------- What is a Dynair® Ballcushion? The Dynair Ballcushion is an inflated and dynamic therapy and training tool made of patented Ruton. It is a space saving alternative to an exercise ball and is being used as an unstable surface for back and fitness training. It features a needle valve for regulating the air charge. The Dynair Ballcushion can bear a weight of at least 200kg.The material is odourless and free of latex and forbidden phthalates. It is produced in Germany by TOGU-Gebr. Obermaier oHG – the spet for inflatable training and therapy equipment. The manufacturer offers a 30 year warranty for the product. What is it good for? For a strong and y back and a stable core. The back is very effectively relieved and becomes incidentally trained. It can help to avoid pain in the intervertebral discs and strengthen the spinal muscles. The upright posture can be optimized. In addition the following affects can be observed during a sensorimotoric training (interaction between nervous system and muscles): improvement of the nervous system, concentration and coordination, and the stability of joints. How does it work? The air charge in combination with the patented form and the special, high quality material make a dynamic sitting and training possible. Place the Dynair Ballcushion on a seat. While sitting on the Ballcushion minimal movements are necessary to counterbalance the instable surface. These movements are performed by the back muscles. So without spending time for any additional exercises, the back muscles can easily be trained at the office or at home. Additional exercises can be performed, standing on this tool to improve balance (especially the coordination between brain and muscles), joints stabilization and to strengthen and tone core muscles. The Ballcushion can be inflated or deflated for various levels of comfort and difficulty. Hint The Ballcushion is prefect because it is saving a lot of space compared to a ball. At first you feel this wobbly cushion underneath you. You get used to it quickly and just after a short while you realize: There is something happening with my body! I sit more upright, I compensate permanently in order to keep balance and I feel my back muscles working. As my back pain gradually disappears, my impression of doing something good for my is reaffirmed.
