There are many pages on the Internet providing information about the exercise ball / pezziball and sitting ball. Unfortunately, these websites are mostly difficult to find. Often these are also Internet forums where unskilled ideas are often found. Nevertheless, these forums are quite suitable for the exchange of experience.
In order to close these gaps, we have put together some informative books and DVD’s at reasonable prices.
