A gym ball is a soft ball with a diameter of approximately 35 to 85 cm and filled with air. The air pressure in the ball can be easily adjusted and is most often used in physical training and exercise by sitting, lying or balancing on the gym ball.
A primary benefit of exercising with gym balls as opposed to exercising directly on a hard flat surface is that the body responds to the instability of the ball to remain balanced, engaging many more muscles. Those muscles become stronger over time to keep balance. Most frequently, the core body muscles — the abdominal muscles and back muscles — are the focus of exercise ball fitness programs.
We have a range of gym balls for you to choose.
