I've had very good results with a physio who specialises in bone health. Recommended by my GP.
I 'm 76 (menopause at 41) and now doing 24K kettlebell squats in the gym ( Not sure where this one ends!) Plus increasing weights on the leg press. Will have to take anastrozole for at least three more years- a drug very bad for bones, but there seems to be no other choice. I had an aggressive grade 3 hormone-fed breast cancer.
