Thank you for your concern. But Please look up the Liftmor study to get more of an understanding of what it entails. My PT has a doctorate in PT and specializes in osteoporosis and works at our hospital. She was very enthused about incorporating the Liftmor study into my protocol. I had an xray to ensure there were no fragility fractures but the Liftmor program did have participants who did have fragility fracture (just not within a year of participation). No fractures in the two years of the study and they were lifting HEAVY. Gained some BMD. You must take it slow and build up. And work with someone who can help you attain the correct posture and train you properly on the exercises. Also according to the Liftmor program you needed a trained physiotherapist to spot you when you did the exercises.

I walk on the YMCA cushioned track with 4-5 lb weight inside a backpack.
