Hi @vinny101, I guess it depends on a person's resources and what other forms of exercise she or he can perform. The Marodyne LIV cannot run on carpeting so it's not practical for my house. I opted instead to do Dr. Loren Fishman's yoga routine (on YouTube) which has been studied and found to increase bone density, "12 Poses vs. Osteoporosis" if you want to Google it.
Margaret Martin posted a short video on the benefits of the Marodyne LIV:

She explains how it has it has been found to be beneficial for improving the lumbar spine, in post menopausal women particularly when a person's options for exercise are limited.
A few Connect members have posted about using them, but I'm not sure where their comments are. You may be able to find them by searching for Marodyne LIV. Best, Teri
