Is strength training actually keeping you healthy, or is it breaking you down?

Spend five minutes on social media and the message is hard to miss: you need to be strength training. And honestly, that message isn’t wrong. Strength training is one of the most useful things you can do for your long-term health, with genuine benefits for muscle mass, bone density, metabolic health, mental health, and the kind of physical capability that makes daily life easier as you age.

But the devil is in the dose.

What I’m seeing more frequently is people lifting more without necessarily moving better, and injuries quietly creeping up as a result. Most people reading this are not 21 anymore. Recovery takes longer, tolerance is different, and the margin for error is smaller. When I was younger I could throw 170kg on a bar without much thought. I can still lift heavy now, but I’m far more selective about when and why I do it, because the risk versus reward equation shifts with age.

Strength training is a tool, not the goal. Done well, it makes life easier: picking up kids, carrying groceries, staying capable as the years pass. But that only happens when the training actually serves you. If you tweak your back chasing a number you weren’t ready for, you haven’t improved your health. You’ve compromised it.

Strength is also always relative. Ten kilograms might be light for someone with 20 years of training behind them, but for someone else it might be genuinely heavy. It depends on training age, bodyweight, the movement itself, and current capacity. A goblet squat and a back squat are not the same thing, even if they look similar on paper.

The issue isn’t strength training itself. It’s the way most people approach it, chasing numbers without asking whether those numbers are actually serving them. Deadlifting 100kg sounds impressive, but the more useful questions are: can you move well afterwards? Does it carry over into daily life? Does it make things better or just inflate a number on a whiteboard?

Most gym injuries come down to poor load management. Too much load, too soon, on movement patterns that aren’t ready for it. As Gray Cook puts it: don’t load dysfunction. When you layer heavy weight onto poor movement, something eventually breaks down. That’s not pessimism, it’s just physics.

The strongest people in the world, competitive powerlifters included, don’t train at maximum intensity all the time. Most of their work sits between 60 and 80 percent of their maximum, with occasional heavy sessions and lighter work to build skill and capacity. They don’t treat every session as a test. Most recreational gym-goers do the opposite, and over time it catches up with them.

A useful way to think about it: hard, medium, easy. Most people try to make every lift feel hard. The people who make the most progress over time get very good at making their medium feel easy, so that when they do go hard, it actually means something.

Strength isn’t forced. It’s built, through consistent work, good movement, and a nervous system that’s had time to adapt. The goal isn’t to see how much you can lift. It’s to make life outside the gym easier, stronger, and more capable.

If your training isn’t doing that, you’re not building longevity. You’re borrowing from it.
