I have been watching an excellent free online summit called More Natural Approaches to Osteoporosis and Bone Health hosted by Marie Bissinger. It started on Monday and each talk or interview is only available for 24 hours (US East coast time). Some outstanding talks have finished but I remember that they do repeat them at the end of the week/week-end.
The talks cover every aspect - exercise, nutrition, supplements, low intensity vibration, HRT, bone profile testing to guide medication options etc. I really recommend Sheri Betz who does a presentation of research then a practical demonstration, also Joan Pagnano and Dr Claudia Tamas ( all on exercise).
It is free though there of course options to buy lifetime access etc which you can ignore! I have certainly picked up some very useful tips.
