Choose countryThe 4FIZJO DONUT AIR BALL is an inflatable exercise ball for fitness, rehabilitation exercises and corrective gymnastics. This black 50 cm version has a flattened ring shape with a central opening.
Shape and exercise options
The flattened shape increases contact with the floor for greater stability during exercise, while the central opening adds comfort. Use the ball for back and abdominal muscle exercises, mobility work and general conditioning at home, in the gym or in a physiotherapy practice.
Material and included pump
Made from PVC, the ball features an anti-burst system that allows air to escape gradually if it is damaged. A dual-action pump with a pull & push system is included.
Preparing for first use
After unpacking, leave the ball at room temperature for approximately 2 hours. Inflate it to 80% of its volume and leave it for 24 hours to allow the material to stretch. Then inflate to its full volume without exceeding the 50 cm diameter and close the opening securely with the white plug.
