How to pump up a fitness ball?
The fitness ball is delivered without air, so you have to inflate it yourself. First fill the fitness ball to approximately 80% of its diameter and let it rest for a day. This gives the material time to stretch and to get in the right shape. After 24 hours the fitness ball can be fully inflated and is ready for use!
