This ball is small, handlcih, compact and super suitable to train. At first, he smells something when you take him out of the package that passes though. I also found class that was equal to a little guide with some exercises there. I use the ball now daily. I have specially got me a DVD in order to do exercises with ball can. It works, if you can overcome your inner couch potato. Class also signals that could be every time let out the air to make him put away to save space. Since I use the ball every day I do not do the course. To inflate a straw has been included, so you do not nukkeln to the plastic * * needs. But this inflation also comes with a standard ball pump.
