@dbamos1945 @deb541 Most kinds of exercise help prevent fractures by helping preventing falls. Unfortunately research shows that for exercise to directly build bone requires heavy-for-you resistance and impact exercise.

Below is a fun video with the top researcher in this area, Dr. Belinda Beck, talking with OsteoBoston. Her LIFTMOR study included a control group that did gentle exercise including light weights; but that group overall lost bone while the gals who were lifting heavier weights and jumping gained bone density.

Great videos exist from lots of experts such as Lisa Moore, doctor of Physical Therapy on how to slowly build up to resistance & impact exercises (eg heel drops). Lots of discussion & links elsewhere on this forum also.
