Strong bones are the armour that carry us through life’s battles — whether it’s racing triathlon, carrying the shopping, or keeping up with grandchildren. Yet too many athletes only notice cracks in that armour when it fails.
In this episode, Simon is joined by Dr Juliet McGrattan and Dr Catherine Jackson to explore what really keeps bones battle ready: the truth about calcium, vitamin D, hormones, strength training, and why endurance sport alone isn’t enough.

Strong bones are the armour that carry us through life’s battles — whether it’s racing triathlon, carrying the shopping, or keeping up with grandchildren. Yet too many athletes only notice cracks in that armour when it fails.
In this episode, Simon is joined by Dr Juliet McGrattan and Dr Catherine Jackson to explore what really keeps bones battle ready: the truth about calcium, vitamin D, hormones, strength training, and why endurance sport alone isn’t enough.
Together, they unpack how both men and women can protect their bone health, maintain strength through midlife and beyond, and build habits that last decades.
Quote of the Episode
“Use your future self as a motivator. I know 80-year-old Juliet pretty well now — and every time I’m doing something good for my bones and longevity, she’s waving her pom-poms.”
— Dr Juliet McGrattan
Key Talking Points
- Bone Health Basics – Why both men and women need to take bone strength seriously, not just post-menopausal women.
- Hormones & HRT – How menopause, testosterone, and modern HRT options affect bone density and long-term health.
- Strength & Impact Training – Why bones need load, impact, and multidirectional movement to stay strong.
- Nutrition Foundations – Getting calcium, vitamin D, and protein right — plus fuelling properly for endurance.
- Sleep, Recovery & Lifestyle – How rest, sleep, and everyday movement protect your healthspan as much as your bones.
Key Takeaways
- Bones need impact – Walking, hopping, lifting, and loading keep your skeleton strong.
- Endurance isn’t enough – Running, cycling, or swimming alone won’t protect bone density.
- Fuel properly – Under-eating and low energy availability are major risks for bone loss.
- Recovery matters – Sleep and rest are when your bones and muscles actually rebuild.
- Train for your future self – Every strength session today is an investment in how you’ll move at 80.
