Muscle one of the strongest predictors of healthy aging

When people hear that muscle is one of the strongest predictors of healthy ageing, I don’t want you picturing huge muscles, grunting in the gym, or trying to “bulk up.

That’s not what this is about.

In a healthy adult, muscle makes up around 40% of total body weight. And its job goes far beyond lifting weights. Muscle helps you move, stand upright, breathe efficiently, store nutrients, and regulate your metabolism like a support system for your entire body. Research consistently shows that muscle strength and cardiovascular fitness (VO₂ max) are two of the best predictors of how long and how well we live. Why? Because they reflect how well your muscles, heart, lungs, and nervous system work together.

Strong muscles don’t just help you lift things, they help you stay independent and capable as you age. One of the biggest drivers of long-term health is something called healthspan.

Muscle strength (and maintaining muscle mass) plays a huge role here. And the good news is that your body is designed to respond to the right stimulus. When you train your muscles properly and support them with enough protein, your body adapts by getting stronger. This is why strength training matters.

More and more researchers are recognising that muscle function is one of the most meaningful measures of health.  Real-world strength, balance, and movement matter far more than isolated numbers on a lab test.

At Salus Strength, this is exactly why we focus on purposeful, evidence-based strength training and not extremes, gimmicks, and not chasing aesthetics. Just building a body that supports you now, and for decades to come.
