Gary Rhodes of Screen My Bones gets practical in Part 2: which bone scans are available, what they measure, and how often to retest. He explains the science behind osteogenic loading and BioDensity — a technology that builds bone safely even in people with severe osteoporosis — and covers what someone with no gym access can do. The episode also covers the specific nutrition that supports bone density, including the calcium-K2 relationship that most people get wrong.

Key topics:
DEXA scan: T-score, Z-score, fragility score, TBS, radiation, inaccuracy rate
EchoLight (REMS ultrasound): bone density + quality, no radiation, 5-year risk window
Why the TBS function on DEXA machines is rarely used — and why it matters
Retest frequency: every 12 months recommended vs NHS 3-year standard
BioDensity and osteogenic loading: the science, the safety, Wolff's Law
Power Plate (whole-body vibration) and the Rev Bike (vibration + VO2 max)
Impact vs loading: what each does for bone and whether you need both
Zero-budget bone-building: running, hopping, jumping, heavy lifting
Why cyclists, swimmers, and rowers have unexpectedly poor bone density
EMS (electro-muscular stimulation): role and limitations
Results: bone quality and T-score changes in 6 and 18 months
Nutrition: whole foods, protein, absorption, eating in parasympathetic state
Specific nutrients: D3 + K2/MK-7, magnesium, collagen, boron, Omega-3
Calcium supplementation: why it can cause harm without K2 and exercise
Protein and bone: the muscle-bone connection
