Input:
The pump does the job!  For a small 9" inch exercise ball it takes almost no effort at all, for a larger ball it is a bit more work but not too bad.  The pump held up well through several pump up sessions.

The hardest part of pumping up the exercise ball is removing the air stopper from the ball.  If someone has a trick on how they do it, I would love to hear it!
