Exercise Balance Ball

Dimensioned drawings of various size Exercise Balance Balls with size recommendations for use as an office chair

The Exercise Balance Ball is a rubber or an inflated plastic ball invented by Aquilino Cosani in 1963. First used in newborn and infant treatment programs, you can now find these balls in gyms, exercise class, training grounds, and in physiotherapy classes and are common for individuals and patients who needed personal care from doctors or fitness experts. Nowadays, we use these balls almost in every place including offices, living rooms, private homes, and in sports facilities. Athletes and players use exercise balls as sports equipment to help perform a myriad of exercise or sports by leaning or sitting on the ball while maneuvering or assuming different positions without the support of the arms. The health benefits of using exercise balance balls include maintaining individuals core stability, reducing back and spine problems, keeping the right posture, and for muscle balance.

The Exercise Balance Ball has a range of overall sizes between 21.65”-33.5" (55-85 cm).
