My PT emphatically did NOT recommend Dr. Fishman’s yoga poses, and she is a specialist in spinal health. My functional OB/GYN did NOT encourage me to buy a weighted vest. I have been a Wellen user for the better part of a year, and find it sometimes a bit boring/repetitive, but reasonably priced, and eminently doable and helpful. I used it as part of a successful regimen to turn around my osteoporosis diagnosis.
