#StabilityBall Pinjian Anti-burst and Slip Resistant Strength Exercise Stability Ball with Pump by Pinjian Fitness

This is a great exercise ball. It wasn't difficult to blow up with the manual pump, but did take a little bit of time and physical strength. Once I did it, it was so much to bounce around on it. I love this exercise ball because there are so many different ways to use it for improving your body's posture and tone.
