Size recommendation:
For gymnastics:
Size S = approx. 140 cm - 154 cm height
Size M = approx. 155 cm - 175 cm height
Size L = approx. 176 cm - 185 cm height
Size XL = larger than 185 cm height
If you want to use the exercise ball exclusively as a sitting ball, we recommend choosing a slightly larger ball. You can also vary the size due to the amount of air pumped.
