I am replying in the context of my earlier posting, "The hope is that with the right weight-bearing exercises, you can reduce the bone loss and the consequential calcification." Newton has some interesting observation relevant to what would be "the right weight-bearing exercises". He recommended impact loading. I think the exercise regimen should be determined by a professional (e.g., physical therapist specializing in these matters) specific to the condition of the individual being treated. For example, for someone with severe osteoporosis (common with ADT), the bones may be too brittle to withstand impact loading.

One doctor had recommended to me intermittent jogging.
One form of intermittent jogging: [Warm-up Walk] ──> [10-Second Jog] ──> [1-Minute Rest Walk] ──> [Repeat 10-15x].
In another variation (after warm-up) - more for cardio-vascular health and support for controlling cancer: Jog until the heart rate reaches a certain level (depending on age and condition; for me 102) and maintain that for 1 minute. Then, walk slowly until the heart rate drops to the level normal for walking. Then, repeat the cycle a couple of times.
