@trixiegirl Hey Trixie
First I have not looked into Onero online too much. While I have severe osteoporosis -4.1 is my worst spinal T-Score, I was not starting from the situation of being unfamiliar with exercise. In fact I had a long history of doing different types of exercises and of thinking about exercise and physical activity for health. I am in no way implying that others with different backgrounds and situations should do what I am doing.
I am doing a modified LIFTMOR protocol on my own. I do not go to a gym. I studied, figured out and experimented with what I wanted to do over an extended period of time while I tried other things like Marodyne and heel drops and bodyweight exercises. I also had a visit with a very knowledgeable sports doctor to have him check my form in doing the exercises.
I would have liked to have gone to Australia and gone to Belinda Beck's facility but that was not possible for me. I did what I could do under my circumstances. While I respect their efforts to bring the fruits of their studies to everyone safely, I just do not think squats, deadlifts, military presses and jump drops are something that cannot be done on one's own. At least for those with the right background and starting point.
Anyway, not encouraging others to do what I'm doing.

It's interesting to think about risk in the broad sense with osteoporosis. There is risk in lifting weights intensely or in doing other forms of exercises or sports intensely. But there is also risk in being inactive. Inactivity has long term risk mostly while with exercise and osteoporosis we fear the short term risk. The drugs for osteoporosis have all kinds of risks. Not taking them if you have severe osteoporosis has the increased risk of fracture. Each person has to choose how to navigate those risks. From the outside some of my choices might seem strange. I stopped playing badminton and pickleball considering them too dangerous for my degree of osteoporosis. OTH I am lifting weights. The osteo specialist I see recommended I continue pickleball. I loved playing pickleball but much of what I loved was playing intensely with lots of running, twisting, doing whatever possible to get to every ball I could. So for me, pickleball was risky. My modified LIFTMOR is done slowly, carefully, with no sudden unpredictable moves and twists and I saw that as reasonable risk. Besides one of those activities might help bone growth a little bit and the other might help bone growth a lot. I now play Beat Saber as a safe substitute for badminton and pickleball. And I take Evenity choosing the potential bone growth over the fear of possible untoward effects. I struggled over each of those choices. It seems that navigating these struggles are what we are doing on this forum.

I don't use the Marodyne at this point because I'm doing many other things to help my overall health that I'm confident are helping me.
Good luck to you in your quest
