The 3 Most Important Types of Exercise for Longevity
Why walking alone isn’t enough — and what to prioritise after 40.
People often think longevity is just about living longer — but that’s only half the story.
For me, longevity means:
Avoiding chronic diseases that become more likely with age
Being able to play catch and lift my great-grandkids at 90
Caring for the one body I’ve got — out of respect for myself and those around me
Exercise is a major part of that puzzle.
“Getting it right” in your 40s–60s shapes how you’ll live in your 70s, 80s, and beyond.
And while it can feel like a big time investment…
…you’re not losing time — you’re saving it.
Because you’re adding years to your life, and quality to those years.
This week’s newsletter covers:
The top 3 types of exercise for longevity
Why walking alone isn’t enough
Why resistance training matters more as we age
A simple weekly routine you can personalise to your life
🧬 #1 Walking & Aerobic Fitness — Your Foundation
Think of this as engine maintenance for your body and brain.
Why it matters:
Strengthens your heart and lowers blood pressure
Strongly linked to lower chronic disease risk (7,000+ steps/day)
Boosts mood, stress resilience, and creativity
Reduces inflammation and supports cellular health
It’s free, low-impact, and easy to sustain
A good target is 150+ minutes per week of moderate effort — walking counts if it’s brisk.
On 2–3 days each week, try to make your walks brisk (Zone 2), or swap one for a jog, cycle, or swim.
This is your foundation — the habit that literally keeps your body alive and your brain sharp for longer.
💪 #2 Resistance Training — Your Key to Staying Independent
I talk to so many people in their 50s and 60s who care about their health, yet don’t feel the need to start strength training.
From around age 40, we naturally start to lose muscle (sarcopenia).
If we do nothing, that’s 1–2% of muscle mass lost per year after 50 — up to 40% gone by 70.
This is the main driver of frailty and loss of independence.
Just two sessions a week of resistance training (using bodyweight, bands, or weights) can stop — and even reverse — that loss.
Focusing on legs, core, and posture muscles is especially important.
Building and using your muscles also helps regulate blood sugar because muscle tissue acts as the body’s main “glucose sink,” and contracting muscles also trigger the release of anti-inflammatory signalling molecules called myokines.
It’s never too late to start. What’s often seen as “normal aging” — frailty, fatigue, loss of strength — is not inevitable.
Read on for the optimal weekly protocol I recommend if you’re just getting started.
⚖️ #3 Balance & Mobility — The Unsung Protector
Around 1 in 3 adults over 65, and half of those over 80, experience a fall every year.
It’s not just the fall itself — it’s what comes after that shortens lifespan:
Introducing some balance and mobility work helps prevent that cascade.
It keeps your joints flexible, reflexes sharp, and trains your nervous system and proprioception — your brain’s awareness of where your body is in space.
Simple ways to start:
You don’t need an hour-long yoga class (though those are great if you enjoy them) — just 5 minutes of balance work each day can make a huge difference.
It can be as simple as doing single-leg stands for two minutes while brushing your teeth.
Think of it as future-proofing your freedom of movement.
