Stronger, Not Softer: Why Strength Training Matters More After 40

This article is part of the CrossFit BC journal, written by the coaching staff who run our classes in Olympic Village, Vancouver. We publish what we teach on the floor: training decisions, recovery, nutrition, and the honest tradeoffs behind them.

Common questions

Is strength training safe after 40?

Yes, and it is one of the safer forms of exercise when coached properly. Most adult injuries from lifting come from poor programming or chasing weight before competence. With a coach and a sane plan, strength training in your forties, fifties, and sixties has lower joint stress than running and lower fall risk than nothing.

How often should I strength train after 40?

Two to four sessions a week is the sweet spot for most adults. Twice a week is enough to maintain and slowly build. Three to four sessions is enough to make real progress and rebuild what age has been quietly taking. Quality and consistency matter more than volume.

Will strength training make me bulky?

No. Building meaningful muscle takes years of dedicated work, even for younger adults. After 40, your hormonal environment makes it harder, not easier. What you will get instead is better posture, more energy, more capable joints, and a body that feels lean and strong. The bulky concern is a marketing myth.
