He is not an osteoporosis expert, although he is fast becoming one! He is highly educated, works out of a hospital rehab setting, so he’s experienced with older folks. The most important thing is that he listens to me….when I am in doubt about some movement, he adjusts it, but he also challenges me when I need a bit of encouragement to progress to a higher level of difficulty or increased weight. His program is always functional-movement oriented and always explains the why and how of each exercise. We moved VERY gradually, so over 18 months, I feel like I have come a long way, but everything was at a safe pace. It’s hard to find someone without a recommendation. I think you wrote that you had seen a physical therapist?? Might ask them. I started this whole process with physical therapy for a sore back (not a fracture) and she was good about proper form and helping me with that issue. Once I felt confident, I moved on with the trainer. Call your local hospital to see if they have any programs like this one. Local Ys usually have trainers on staff. It’s not cheap, but worth it if you find someone you trust.
