My name is Tracy Sharpe.  For several months I have being taking the OsteoUp class.  I started to see a difference almost immediately.  When I took the first class I felt stronger. The same has been true for every class I have taken.  I have a knee that I have a screw in. For that reason, I have not felt confident enough to do exercises involving my knee.  My knee feels stronger.  I cannot say good about OsteoUp.  I would highly recommend it.
