The Gymnic Exercise ball is the most sturdy and non-burstable exercise ball that I have purchased. It was recommended by a physical therapist, after I had tried several other brands and types. I am quite please how sturdy and durable the ball has been and would recommend it to anyone with a need to work in an exercise program. Because it is so sturdy, I also use the ball as the seat for my desk, because it helps me balance and keep a proper posture, while exercising my stomach and leg muscles.
