The big gymnastic balls, used for over three decades in therapy, have conquered many other fields of use. These balls can now be seen in gymnastics and sports, at schools, and in offices. However, we have not forgotten about the special needs of therapy. One of the biggest advantages of the Gymnic Line is its versatility. Dynamic sitting positions, training, and therapeutic exercises are connected closely and should not be looked at seperately. These are the Big Daddys of the gymnastic balls! Whatever your needs are, choose the one ball that provides all, the best ball, the Gymnic MegaBall! Available in 150 or 180 cm sizes.
