Frequently Asked Questions

How do I choose the right exercise ball size?
When seated on the ball with feet flat on the floor, your hips and knees should be at approximately 90 degrees. The 34-inch (85 cm) ball is recommended for users 6 feet 4 inches and taller. If you are shorter, a smaller size (55 cm, 65 cm, or 75 cm) will provide better alignment.

Is a pump included?
No. A standard hand or foot pump is required to inflate the ball and is not included. Most standard ball pumps with a needle attachment are compatible.

What exercises can I do with this ball?
The included multi-language exercise instruction chart provides guided exercises for core strengthening, flexibility, balance, and rehabilitation. Common uses include seated balance exercises, core stabilization, stretching, and physical therapy protocols.

How do I know when the ball is inflated to the correct size?
Inflate the ball until it measures approximately 34 inches (85 cm) in diameter. A soft measuring tape or a wall-and-ruler method can be used to check the diameter. Slightly underinflating the ball (by 1 to 2 cm) can make it more comfortable for beginners or rehabilitation use.
