Many thanks, WS. I will order one and take a look at the site /videos soon.
Also, I am assuming that my 'regular' PT program (these are a group of doctor of physical therapy and their assistants for exercises one-on-one) while not geared to osteoporosis will be OK too. I'm pretty much at 'square one' due to not working out at all during 2020-now, just starting up in the last months. (I also do a few things at the gym).
