Perfect for the exercises I need to do. I love it!
great for sitting on but on small side for men to get good work out on.
This exercise ball is a good deal for the price. It was a little smaller than I thought it would be, but is works well enough for exercise. The thing that is not good about the ball is the pump. The instructions say not to use a generator pump, but if you don't you will NEVER fill this ball up. Using the air pump that comes with the ball is just awful. It is useless! If you want to work your arms out and take forever to fill up the ball with air then use the air pump. This pump is not worth using. Use a air generator/bike pump generator to inflate this ball. If you are concerned regarding the ball inflating too much then read the instructions that tell you how large it is supposed to get when filled with air and how to use a measuring tape to make sure the air amount is correct.
