I agree that Margaret Martin https://melioguide.com/ is a wealth of information when it comes to everything osteoporosis. The one issue I have found, in general, when looking for osteoporosis related information is that so much of it is geared toward 70+ y.o. people. I was diagnosed with osteoporosis 4 yrs ago at age 50 (L1-L4 average t-score at that time was -3.9) and when I researched safe exercises, I found everything to be way too easy. I asked 2 doctors, my endocrinologist and an orthopedics doctor and my endocrinologist stuck w/ the unhelpful light weights and walking—if this could help me, I wouldn’t have osteoporosis because I’ve been doing both of these things my entire adult life—and the orthopedics doctor suggested I take up running. I was able to get a few session w/ a physical therapist, who works at an orthopedics medical practice. She didn’t have any real experience working with ppl with osteoporosis because apparently most ppl w/ osteoporosis don’t seek out this type of help and the exercises suggested by the physical therapist were too easy for me so I quit physical therapy and joined a gym and have gradually increased my weights. Note, I haven’t had any fractures and I’m just hoping all my hard work will pay off—I’ve been going to the gym 3 days a week since January 2022.
