Hi @ellerbracke, Carol Michaels and Sara Meeks have good exercises for osteoporosis posted on YouTube. American Bone Health also has a resource, Exercises for Bone Health, which you can Google. My husband broke his hip recently and many of those exercises are ones the physical therapist gave him to strengthen his hip.
I've added light weights and also use exercise bands to increase resistance.
My rheumatologist told me a weighted vest could cause spinal fractures - so I gave the one I had, 10 pounds, away.
I came across an article a while ago that said women who gardened had less osteoporosis. I think you have to be careful, not to bend the spine forward, twist too far or lift something too heavy weight. The guidance I've read is no more than 20 lbs.
A review of studies involving whole body vibration therapy can be found in "Whole-body vibration exercise in postmenopausal osteoporosis", Magdalena Weber-Rajek,et al which you can google. All the best.
