Pilates Girls, You’re Losing Bone. The Exercise Science of Building Bone After 40 with Prof Belinda Beck

For decades, women with low bone density were told to take it easy; Professor Belinda Beck's research proved the opposite: high-intensity resistance and impact training safely rebuilds bone, even in women who had been told their bones were too fragile to lift heavy.

Belinda covers the full arc of bone health, from how peak bone mass is set in the teenage years, to what actually happens to bone when estrogen declines through perimenopause and menopause, to why so many popular "safe" exercises, including walking, cycling, and Pilates, simply don't provide enough stimulus to protect bone.

They dig into the physiology of bone remodelling, the real evidence (and lack of it) behind weighted vests, how to read a DEXA scan, and practical calcium and vitamin D guidance. Belinda also shares the story behind LIFTMOR itself, including how her research team was once considered reckless for asking postmenopausal women to lift heavy, and how those same women ended up stronger, more confident, and more independent than they'd been in decades.
