Hi @susanop. I was following your discussion with @chocoholic. I just started taking alendronate for osteoporosis. The diagnosis surprised me as I was an avid exerciser for years. I was hit with an autoimmune disorder when we were in COVID lockdown. The pain was incredible, I still managed a daily hour-long walk, but that was it for the day. I could barely move. My mother and my two aunts had osteoporosis so family history is there, as well as slight build, etc. I'm on a steroid now to manage my autoimmune disorder = more bad news for the bones. Anyway, I've been researching appropriate exercises, especially the work of Sara Meeks and Carol Michaels. You can google them. Some of Sara Meeks's exercises are posted online, and they are subtle. The wrong kinds of exercises can do more harm than good to those of us with osteoporosis. I also read about Whole Body Vibration exercise for osteoporosis and purchased a vibration plate exerciser online. The studies I read about that improved bone density had participants on the machines 2x a day for 15 minutes, 5 days a week, for a year. I watch tv while I stand on the vibration plate and use the automatic programs the manufacturer said improve bone density (let's hope!). It's not a hardship, but as with everything else, whole body vibration, at the wrong intensity, might not be good for those with frail bones. I'd like to improve bone density and get off the alendronate. Also, bone density is just one indicator of bone health, from what I've read, and it refers to the quantity of bone, not the quality (that's from Sara Meeks). I've been on a plant-based diet for a number of years, but pretty casual about calcium intake. Now, I increased protein and also take calcium, magnesium, Vitamin D, Vitamin K, Boron, L. Reuteri (a probiotic) and plan to add silica soon.
