Resistance training: buying back the decades

Somewhere in your thirties, muscle and strength begin a slow, silent withdrawal. Left unchecked it ends, decades later, as the difference between getting off the floor unaided and not. Resistance training is how you keep making deposits against that account.

The mortality data is unusually friendly here. A meta-analysis of sixteen cohorts found muscle-strengthening activity associated with 10–17% lower all-cause mortality, cardiovascular disease, total cancer, and diabetes. And the shape of the curve is a gift to busy people: the benefit peaks around 30 to 60 minutes a week. This is not an endurance grind. It’s a couple of focused sessions.

What “counts”

Cover the major patterns — a push, a pull, a squat or hinge, and a carry — with enough load that the last few repetitions are genuinely hard. Progress by adding a little weight or a rep over time. Machines, free weights, bands, or bodyweight all work; the muscle can’t read the label on the resistance.

Beyond mortality, strength work is one of the better levers for insulin sensitivity and glucose disposal, because muscle is a large sink for blood sugar. It pairs naturally with an aerobic base and with adequate protein — the three foundations reinforce each other rather than compete.
