Someone asked me: “I’m walking 10,000 steps a day. Do I really need to lift weights too?”
Fair question. Walking is brilliant for metabolic health, mental clarity, and longevity. But here’s what surprised me when I dug into the research: your body doesn’t lose muscle evenly as you age. You lose the powerful, explosive fibres first — the ones walking doesn’t even touch.
Dr. Andy Galpin — one of the world’s leading exercise scientists — calls strength training a panacea. That’s his word. Brain health, bone density, metabolism, mental health, longevity. No part of your physiology that doesn’t benefit. And one session per week is enough to see massive benefit compared to zero.
The Fibres You’re Losing (And Why Walking Won’t Help)
Dr. Galpin is blunt about this. As you age, your fast-twitch muscle fibres are lost preferentially. You don’t lose them evenly. You lose the powerful, explosive ones first.
These are the fibres that catch you when you trip. Help you stand up from a chair without using your arms. Carry heavy shopping. Get off the floor without help.
Walking doesn’t activate those fibres. Neither does cycling or swimming. You need high-force production — lifting something heavy, pushing, pulling, squatting. That’s what signals your body: “Keep these fibres. We need them.”
Cardio vs Weights: Renting vs Buying
Think of it this way: cardio is like hiring a cleaner for an hour. House is clean for that hour. The moment they leave, mess accumulates again. You burn calories during the run, then stop.
Weights? That’s installing a dishwasher and washing machine. Upfront effort — learning to lift, building muscle — but now your house is cleaning itself 24/7.
Muscle burns calories at rest, even while you sleep. Cardio is renting. Weights are buying. Both useful. One compounds.
One Day Per Week Is Enough
Here’s the brilliant bit: Dr. Galpin says one strength session per week is enough to see massive benefit compared to zero.
You don’t need five days a week. One session, accumulated over 30, 40, 50 years? Studies on lifelong lifters show superior health markers across every system.
This matched my experience. Early in my journey, I was fasting and walking, but I felt weak. Tired. Added two to three sessions a week — basic push/pull/squat movements — suddenly I had more energy, slept better, and my body composition changed even when the scale didn’t move.
You’re Training for Independence, Not Six-Pack Abs
Strength training is an insurance policy for your independence. You’re not training to compete. You’re training so at 75, you can get off the floor without help, carry your own shopping, play with your grandkids.
That’s the prize. Function.
And you don’t need to join a gym if that feels like a faff. Dr. Galpin confirms you can do this at home with bodyweight, resistance bands, and a couple of kettlebells.
Budget example: £100 gets you two 5kg kettlebells, two 20kg kettlebells, and bands. That’s a lifetime setup.
You don’t need to go to failure or get massively sore. Two sets of eight reps, focusing on habit formation, is sufficient for beginners. The goal isn’t optimisation. It’s consistency. One to three days per week. Forever. That’s the win.
Start Simple
If you’re over 60 or have health conditions, speak to your GP before starting. But don’t let fear of injury keep you sedentary. Done properly, strength training is one of the safest things you can do for long-term health.
Start simple. Bodyweight squats, push-ups, kettlebell swings. Build the habit. Your 75-year-old self will thank you.
🎯 Key Takeaways
- Fast-twitch fibres go first — Walking doesn’t activate the powerful muscle fibres you lose preferentially with age
- One session per week is enough — Massive benefit compared to zero, compounded over decades
- Train for function, not aesthetics — The prize is independence at 75, not six-pack abs
- £100 home setup works — Two kettlebells and bands; no gym required
- Two sets of eight reps — Consistency beats intensity for beginners

Someone asked: “I’m walking 10,000 steps a day. Do I really need to lift weights too?”
Here’s what Dr. Andy Galpin — one of the world’s leading exercise scientists — says: strength training is a panacea. That’s his word. There’s no part of your physiology that doesn’t benefit from it. Brain health, bone density, metabolism, mental health, longevity. All of it.
And here’s the bit that surprised me: walking won’t save your fast-twitch muscle fibers. Those are the ones you lose first as you age.
Dr. Andy Galpin is blunt about this. As you age, your fast-twitch muscle fibers are lost preferentially. You don’t lose them evenly. You lose the powerful, explosive ones first — the fibers that catch you when you trip, help you stand up from a chair without using your arms, carry heavy shopping.
