Product Description:
Simple, versatile, and fun to use, the Firm Core Stability Ball is designed to challenge your balance, stability and flexibility through various low-impact exercises and movements. Included with the package is a 30-minute core training video that guides you through a variety of techniques that you can adapt to your training, stretching, rehabilitation or other workout routines. The ball is made of tough, burst-resistant plastic, a special material that resists tearing and, if punctured, deflates safely and gradually. Available in several fashionable colors, the 55-centimeter ball is sized for users measuring between 4 feet, 8 inches and 5 feet, 3 inches.

Rating : - Stability Ball - 55cm "The Firm"
I love this ball. Like some of the other stability ball reviews, I thought at first it was going to be too small, but it's not (I am 5'2"). The 65cm would have been too large I think. It has a DVD workout video with it. Comes with a hand pump - I used a different pump to inflate the ball faster but at least it comes with one. Like the instructions say, the ball appears small at first, when first inflating. Over the next day or so, the ball adjusts and you pump in more air.

Like the color too! Would recommend.
