The excercise balls I have noticed are being pushed in sports stores pretty heavy lately. They use different types of therapy to sell them as well. I noticed one that said it was an ab cruncher, and another that said it could be used for yoga. I have had mine for about 7 years now, and it is very useful for stretching. I was prescribed the excercise ball by a PT as well. The one thing I find that is important is to keep it full with air because when they aren't firm I don't feel that the results are the same. Also, they are great for kids to bounce around on as well as us.
