Give Me Strength

We’re turning into a nation of middle-aged weaklings, experts say, and need to step up the exercise intensity.

This is a story about exercise, but not as you might know it. This is not about toning your ass, as much as saving it. You’ve probably heard it all by now – how a brisk 30-minute walk five times a week can add years to your life. But now there’s growing evidence that you’ll need to work much harder than that to ward off a future of frailty.

“We’re the under muscled generation,” says Auckland University nutrition professor David Cameron-Smith. For too long, he says, we’ve focused on our heart and brain health at the expense of what he calls our most significant tissue – our muscles. The modern world makes it easy for us to go through life without the intensity of exercise our ancestors did: we are rarely required to lift, pull or push. The result, he says, is “an epidemic of frailty. We are just puny compared to previous generations.”

In middle age – which he categorises as 30 to 60 – we’re embracing a false sense of wellness, he says. We’re juggling a job, child or senior care, and increasingly complex lives, but most of us are fortunate enough to have no obvious disease. At the same time, however, we’re beginning to lose muscle mass and strength. The loss begins in our thirties and accelerates from our mid-forties. And for many years, we hardly notice.
