When most people think about muscles, they think about movement, or appearance. But muscles are far more important than many of us realise.

In recent years, researchers have increasingly described skeletal muscle as an endocrine organ – in other words, an organ that produces its own hormones and signalling molecules, in the same family as the thyroid or the pancreas. In simple terms, muscles communicate with the rest of the body by releasing signalling molecules during exercise, and these appear to influence everything from inflammation and metabolism to immune function and even brain health.

That rather changes how we should think about strength training.

It’s not really about how you look

Building and maintaining muscle isn’t simply about aesthetics. It’s deeply connected to long-term health and resilience – the kind that lets you carry the shopping, get up off the floor easily, and stay steady on your feet well into later life.

As we age, muscle mass naturally declines in a process known as sarcopenia. Left unchecked, this gradual loss can affect mobility, balance, metabolic health, independence, and overall quality of life. It’s not dramatic day to day, but it adds up quietly over the years, and then you suddenly realise that you can’t do the things that you used to be able to do easily.

The encouraging news is that resistance training remains one of the most effective tools we have for slowing, or even reversing, many of these changes – at almost any age.

You don’t need to become a bodybuilder

Importantly, strength training doesn’t need to be extreme. Simple movements performed consistently can have a profound effect. Bodyweight exercises, resistance bands, dumbbells, machines, and even walking uphill all challenge the muscles and encourage adaptation.

At Power of One Fitness, I often remind clients that the goal isn’t necessarily to become a bodybuilder. (Although I can create a programme for you to do that if you’d really like to!) On the whole the goal is to remain physically capable, resilient, and healthy for as long as possible.

Muscle supports posture, protects joints, helps regulate blood sugar, maintains metabolism, and preserves strength during ageing. It also, rather quietly, contributes to confidence.

The mental side of feeling physically capable

There’s something deeply reassuring about feeling physically capable in everyday life. Perhaps that’s one reason strength training so often improves mental wellbeing too – feeling stronger physically frequently changes how people feel emotionally. Fewer aches, more energy, and a sense that your body has your back.

Exercise isn’t simply changing the body. It’s supporting the entire system – joints, hormones, mood, and mind, all at once.

Your muscles aren’t just there to look a certain way. They’re active participants in your long-term health, resilience, and quality of life.
