Glymnis Exercise Ball
Exercise ball is your best fitness partner at home and in the office.
If you think the exercise ball is too small after the first inflation
Check the weight of the ball:
55 cm: 900g, 65cm: 1000g, 75cm: 1200 g
Check the flat diameter of the ball:
Measure the flat diameter of the ball. This size is about 7 to 9 cm larger than the original size.
Due to the long-term folding and storage, the fitness ball cannot reach its original size. Please inflate to 90% first, then wait a day later and then inflate the ball.
