After regular use for a/b a month, the ball burst on me and it hurt! I didn't even overinflate it. I wanna sue the company. The pump is also of poor quality. You got what you paid for.

After about a month of regular use the ball burst. This product is not made to last in the home gym. I am extremly dissatisfied with this product. Save your money, do not purchase this item.

This review is from: SPRI 1B4ALL-55 One-Ball-For-All Kit with 55-Centimeter Ball, Pump and Exercise Chart (Sports)

Exercise books say that the correct size ball is determined by when one sits on the ball, one's thighs and shins should form at least a 90 degree angle: thighs should be more or less parallel to the floor. DVDs I've seen show demonstrators using balls where the thigh-shin angle is at least 90 degrees or greater.

People who are 5'4" or shorter should use the 55 cm ball. I'm 5'3" but found the 55 cm ball to be too small. Even when inflated to be quite taut, my hips are still lower than my knees when sitting on the ball. Perhaps a consideration is one's weight relative to one's height? If one were relatively lighter, one would not compress the ball quite as much.

With a bigger ball, one could inflate it less to achieve the correct thigh-shin angle whereas with a small ball, the only recourse is to lose weight.

On the other hand, when lying on the ball to do chest presses, a smaller ball would allow the elbows to reach closer to the floor thereby expanding the chest more than with a larger ball.

A smaller ball is more challenging -- there is less distance to travel before one would fall off, so it is harder work to use a smaller ball.

The pump is a joke, a real bicycle pump would be more efficient. The ball's valve is also a joke -- not well made but it's good enough, it works. The chart is useless -- spend the money on an actual exercise book.
