Would have been nice if it came with a couple photo instructions on what exercises to do with it. 2 stars

Exactly what I expected! I've been using the ball with a daily exercise routine and have started to see results already in just a few weeks of use. I'm very pleased with the product quality,the price, and how quickly I received my order. 5 stars

I was told several years ago to do crunchs for the never ending lower back pain that I have been experiencing for years. Well doing crunches flat on the floor was very uncomfortable, which made it harder for me to want to do them. Then I found the pilates ball, and all the neck strain that goes with regular crunches does not exisit when doing crunches with the ball just below the curve of the lower back. 4 stars

This ball is great. I had relatively strong abs but not really any definition. I need to do at least 100 situps before I can feel the burn and that takes a lot of time and is uncomfortable. With the ball I do less sit-ups and my abs are becoming more defined. I don't use it all the time so I can't attest to weight loss, but it does work well on your abs for definition. 4 stars

I looked at several therapy websites to find the perfect sized ball from my 2 1/2 year-old autistic son to use to bounce on - everything was too big and too expensive. This ball is just the right size and price and it was delivered quickly. 5 stars
