Your body is ageing.
Do you have a plan for that?
Longevity by Design is a measured, structured programme that builds the physical capability you'll need for your best decades ahead — with a personalised proof loop that shows it working.

The numbers most people don't see
After 30, adults lose 3–8% of muscle mass per decade without structured resistance training. By 70, that loss can mean the difference between independence and dependence.
Falls are the leading cause of injury-related death in over-65s in the UK. Most are preventable — with the right balance, strength, and mobility work started years earlier.
The average person spends their last 10–15 years in significantly reduced physical capacity. Not because it's inevitable — but because no one showed them the levers that could change it.
Here's the good news: genetics account for less than 20% of how you age. The other 80%+ is modifiable — through the right movement, recovery, nutrition, and consistency.
The question isn't whether you'll invest in your health. It's whether you'll do it proactively — or wait until you're forced to.

Measure
A personalised longevity report maps your current trajectory — where you stand, where you're heading, and the specific levers that matter most for you.
Build
A structured, safety-first programme builds your physical capability in the right order: mobility and control first, then strength, then cardio capacity.
Prove
Re-run your report at intervals. See the trajectory shift. Adjust. This isn't motivation — it's a feedback loop that keeps you on course.
Maximum return on your time
You don't need hours in the gym. You need the right inputs.
Research shows that 3 × 1-minute high-intensity intervals can produce comparable VO₂ max improvements to 60 minutes of traditional steady-state cardio. That's the kind of leverage we build into every aspect of your programme.
We identify the minimum input that creates the maximum physiological shift — for your starting point, your schedule, and your body. Your time matters. We don't waste it.
This isn't about doing less. It's about doing what actually moves the needle.

Is this for you?
This is for you if…
- You're 40–65 and want to stay physically capable for decades — not just "healthy on paper"
- You train but have plateaued, or you're active but unsystematic
- You have niggles, stiffness, or minor injuries and want durability — not hero workouts
- You're busy and need a programme that respects your time
- You want structured progress with measurable proof — not just encouragement
- You're ready to commit, not just "try"
This isn't for you if…
- You're looking for hacks, shortcuts, or magic supplements
- You want a diagnosis or medical treatment — this is a capability programme, not a clinic
- You're not willing to log your progress or follow the gates
- You want someone to tell you what you want to hear rather than what will actually help

25 years in holistic health. An engineering background that demands measurement and proof. A decade focused specifically on longevity.
I'm 50, with four children under 12. I ran my own longevity report: biological age 42.2, ageing rate 0.84. I know exactly where my weak points are — and what I'm doing about them. That's what this programme gives you: the same clarity, the same system, and someone in your corner who's doing the work alongside you.
