A good thing to have,
This review is from: Reebok Gym Ball with Pump and DVD - 65 cm [DVD] [Region 0] [US Import] [NTSC] (Sports)
This is a really nice way of working on your posture. Having done yoga for a little while, work with the ball made me realise I don't use all muscle groups to their fullest extent in my yoga practice. I use it for sitting on a few times every day, especially when using my laptop -like now.
The thing is sturdy, bouncy, generally of good quality and has slightly sticky feel so you don't slide off it.
Only 4 stars because the pump supplied didn't work (so gave my lungs a bit of exercise!), and the technical quality of the DVD supplied wasn't brilliant (the content is nice: well presented, motivating and provides sufficiently detailed instructions).
There are cheaper alternatives if you don't want a DVD and a (defect) pump with it, but for me this purchase was fine.
