1: When you play, you should have moderate strength, so that you can use it for a long time, and the service life of the fitness ball will not be greatly reduced because of excessive use.

2. Do some maintenance in a planned way. The reason why the wooden fitness ball cracks is probably dryness. If it is too dry and not maintained, wood products are prone to cracks. Some vegetable oil can be cut off for maintenance, and oiling can keep wooden items tough and not easy to crack.

3. The crack is also caused by the quality of the fitness ball itself. It is suggested that if you want to play fitness balls for a long time, you should buy better quality ones. Once the poor quality fitness ball is bought back, there will be internal problems, and no matter how it is maintained, it cannot be preserved for a long time.
