Sitzball ABS, 55 cm, 120 kg max., Silver <b>What is a Sitzball® ABS®?</b>
It is an inflatable and burst proof gymnastic ball with a patented ABS Anti Burst System - made in Germany. The material called Crylon is odorless and very resilient (max load up to 500 kg/ ABS guarantee up to 120 kg). It is free of latex and contains no forbidden phthalates.

<b>What is it good for?</b>
For safety while sitting or performing exercises due to its ABS System which makes it guaranteed burst proof up to a 120 kg of dynamic load (See Explanation below). Sitting on the Sitzball ABS can help to avoid back pain through. Abdominal and back muscles can be strengthened through safe, efficient, and dynamic back and stability exercises.

<b>How does it work?</b>
While sitting on the ball an upright posture is assumed almost automatically by the upper body. At the same time the pelvic floor-, abdominal and back muscles are inevitably being used for balancing. This permanent activity strengthens the muscles.

<b>Explanation ABS and Burst Proof</b>
The ABS System is a special molecular composition of the ball that prevents it from bursting even when damaged or penetrated by a sharp object. The molecular structure does not allow a whole to grow rapidly faster and rip the ball apart. In case of any damage the ball looses air slowly and leaves enough time for its user to get off safely. There is a difference between the total load a ball can withstand when not damaged, and the maximum load that is allowed for the ball to stay burst proof even when harmed by an object. The Sitzball ABS can withstand a weight of 500 kg if undamaged and is guaranteed burst proof up to 120 kg of weight even when penetrated by a sharp object. This weight is considered to be dynamic. That means a person moving on the ball can weigh up to 120 kg.
