https://firmafitness.ee/wp-content/uploads/2021/12/voimlemispall-1024x683-1.jpg1024683A stability ball is perfect for exercising or to be used as an office chair. The ball has an ABS (Anti Burst System) system, which means that the ball does not break when it explodes, but when it breaks, the air comes out of the ball slowly. The gymnastics ball must be chosen according to its length. The most suitable gymnastic ball has the hips a little higher than the knees.
