I agree with what everyone is say. I was dx with OP in 2024. I was also a runner. I had to stop because I fractured my foot. Then just couldn't get back to it after I healed. So I walked instead. I started Strength, Balance, impact training after the Dx. I also looked at my diet, improved protein intake, get my calcium from food only now. (Seen calcium chews if needed), I started HRT at 70. I am 71 now and have reversed mu osteoporosis back to osteopenia.
