Use It or Lose It
If the phrase "muscle building" conjures up images of sweaty gyms, neon-coloured protein shakes, and people half your age lifting things that look far too heavy, you’re not alone. For many women, strength training simply doesn’t feel like something for them. Plus, they’re busy navigating the school run, demanding careers, or dealing with the delightful unpredictability of the menopause.
But here’s the truth, backed by some pretty serious science: as we get older, muscle isn't just about looking "toned" in a sleeveless top. It is, quite literally, the scaffolding that keeps our lives together.
If you’ve noticed that your shopping bags feel a bit heavier lately, or that getting up off the sofa requires a bit more "oomph" than it used to, you’re not imagining it. It’s a natural process called sarcopenia - the age-related loss of muscle mass.
The good news? We can absolutely do something about it.
1. Keeping Your Independence and Your "Get Up and Go"
Muscle mass is the currency of independence. Science shows that from our 30s onwards, we can lose between 3% and 8% of our muscle mass per decade if we aren't careful.
Think of your muscles as your internal "lift." They are what allow you to hike up Arthur’s Seat, carry the heavy bags of soil in the garden, or simply get through a long day on your feet without feeling like you’ve run a marathon. By maintaining that strength, we aren't just "staying fit"; we’re ensuring that we remain in charge of our own lives well into the future.
2. The Metabolic Engine
Muscle tissue is metabolically "expensive" meaning it burns more calories than fat, even when you’re just sitting down enjoying a crossword. But you’ve got to build and maintain it!
By building lean muscle, you’re essentially upgrading your body’s engine. This helps manage blood sugar levels and lowers the risk of Type 2 diabetes.
3. Protecting Your Bones
In the UK, 1 in 3 women over the age of 50 will experience fractures due to osteoporosis. It’s a sobering statistic, but muscle is our best defence.
When we engage in resistance training, whether that’s using dumbbells, resistance bands, or even just some heavy tins of beans, the "tug" of the muscle on the bone actually signals the body to create denser, stronger bones. It’s like a structural reinforcement project for your skeleton. Strong muscles also protect your joints and keep you steady on your feet.
4. A Boost for the Brain
It isn't just about the body; it’s also about the mind. There is a wealth of research linking physical strength to cognitive health. Exercise releases those lovely endorphins that help banish the "brain fog" many of us face, reducing stress and anxiety.
There’s also a wonderful sense of empowerment that comes from feeling strong. Knowing you can carry your own luggage or open that stubborn jar of pickles without waiting for help provides a massive psychological lift.
The "Heavy Lifting" Myth
We’ve been told for years that only "heavy" weights build muscle. But the latest exercise science championed by experts like Dr Tony Boutagy, tells a much more encouraging story.
The secret?
Your muscles can't actually tell how much a weight weighs. They only know how hard they are working. Research shows that lifting lighter loads (like smaller dumbbells, resistance bands, or even just your own body weight) can build just as much muscle as the heavy stuff, provided you perform the movement until the muscle feels genuinely tired (what the pros call 'training to volitional fatigue').
This is a total game-changer for several reasons:
- Kinder to the Joints
Using lighter weights or resistance bands puts less stress on your knees, shoulders and hips while still giving your muscles the "message" they need to grow. This is great news, especially if you are just starting out. - Accessible Anywhere
You don't need a fancy gym membership or a rack of iron. A set of resistance bands tucked in a drawer or even a couple of full water bottles can do the trick while you're watching the evening news or waiting for the potatoes to boil. - Focus on Form
It’s much easier to keep good form and avoid injury when you aren't wobbling under a massive weight. You can focus on the squeeze, the movement and the breath. - The Bottom Line
You don’t need to become a competitive weightlifter (unless you want to, in which case, go for it!). Do what you enjoy and do what you can do consistently. Whether you’re lifting a kettlebell or just lifting yourself up a Munro, your body will thank you for the effort.
It’s never too late to start. Your future self will thank you for the extra bit of muscle you build today.
