I think you've gotten great advice from windyshores. My bones are much worse than yours, and I am a fervent believer in any exercise that strengthens my body and above all improves my balance - a fall is your worst enemy. But don't count too heavily on an endocrinologist - the one I went to wanted to put me on Reclast and I refused, but I have refused all meds since a switch from Actonel to Fosomax caused a gerd reflex. Don't forget too that bone density is not everything - bone quality is important too.

And I totally agree with your feeling that doctors are being influenced by pharmaceutical companies.
