Hi @bronmeg1,
Like @primek has said, your team will probably put you on Prolia which will help with the bone metastasises. I do attend exercise classes for bone strengthening as @socoda has said but I do not have bone metastasises, just bone density issues. The classes I attend are designed and run by an exercise physiologist. Ask your team if they think that seeing an exercise physiologist would be beneficial. An exercise physiologist can design an exercise program suited to your individual situation.
I hope that you soon have a plan from your doctors and that will help you to start feeling better and moving forward again. Take care.
