Most training advice after 40 has one instruction underneath it: get stronger. Lift heavier. Add load. And that advice isn’t wrong, strength matters enormously through perimenopause and menopause, and I’ll never talk anyone out of it.
But there’s a second quality that tends to decline faster than strength, rarely gets trained on purpose, and quietly shapes how capable and confident you feel in everyday life. It’s called power. If strength is the headline, power is the fine print most women never get to read.
Strength and power aren’t the same thing
Strength is how much force your muscles can produce. Power is how quickly you can produce it. Force multiplied by speed.
It’s the difference between slowly standing up out of a low chair (strength) and catching yourself the instant your foot slips on a wet floor (power). Between carrying a heavy suitcase (strength) and stepping off a kerb, feeling yourself tip, and correcting it before you fall (power). One is about capacity. The other is about how fast that capacity can show up when you need it , which, in real life, is usually in a fraction of a second.
Why power fades first
Here’s the part that surprises people: strength and power don’t decline at the same rate. Across the research on ageing muscle, power falls earlier and more steeply than strength — often meaningfully faster per decade.
There are two main reasons. First, we preferentially lose our fast-twitch (type II) muscle fibres — the ones responsible for quick, explosive contractions. Slow-twitch fibres, the endurance ones, are far more stubborn. Second, the speed of the signal from brain to muscle slows down. So even when strength is holding up reasonably well, the ability to fire fast is already slipping.
The consequence is that you can be training consistently, genuinely getting stronger, and still feel a little unsteady, a little slower to react, a little less sure of yourself on uneven ground. Not because you’re unfit — because you’ve been training only one of the two qualities that keep you steady.
The menopause accelerant
For women, this doesn’t happen in a vacuum. The fall in oestrogen through perimenopause and menopause accelerates the loss of muscle mass and strength — oestrogen has a genuine role in maintaining muscle and connective tissue, and its decline speeds up changes that would otherwise arrive more gradually. Layer a naturally faster decline in power on top of a menopause-driven decline in muscle, and you have two trends pointing the same unhelpful direction at once.
This is exactly why “just keep lifting” — while good advice — can leave a gap. Traditional slow, heavy strength work builds force beautifully. It doesn’t necessarily train speed.
Why this matters more than performance
If power were only about athletic performance, it would be a nice-to-have. It isn’t. Power is one of the strongest predictors of physical function and fall risk as we age — in several studies, muscle power tracks with everyday function and fall prevention even more closely than strength does. And falls are not a small thing: they are one of the biggest threats to independence in later life.
The encouraging half of that story is that power responds to training. Systematic reviews of power training in older adults show meaningful improvements in the functional tasks that map onto real-world stability — getting up, moving quickly, reacting. This is trainable. It just has to be trained deliberately.
How to start — without overhauling your routine
The best news is that you don’t need a new programme, new equipment, or anything intimidating. You need to add intent to move quickly to movements you may already be doing — safely, and in small doses.
The principle is simple: lift or push with a fast, deliberate “up,” then lower under control. The concentric (lifting) phase is where the speed goes; the lowering stays slow and controlled to protect joints.
A few practical ways in:
- Sit-to-stands, but faster. Stand up from a chair as quickly as you comfortably can, then sit down slowly. That’s a power rep.
- Fast concentric on moves you already do. On a squat, leg press, or step-up, drive up quickly, lower slowly.
- Low-impact “pop.” Heel raises done briskly, or a gentle step-up with a quick drive through the standing leg.
- Keep the reps low and the quality high. Power is about crispness, not exhaustion — think 3–5 fast, clean reps, then rest. Stop well before form gets sloppy.
Add this to two of your existing strength sessions a week. You’re not replacing your strength work — you’re adding the layer underneath it.
A sensible caveat: if you’re new to training, have joint concerns, or any balance issues, start with the fast sit-to-stand and build from there, ideally with guidance. “Explosive” should always mean controlled and deliberate, never reckless.
The takeaway
Strength keeps you capable. Power keeps you quick — and quick is what catches you when life moves faster than you expected. After 40, and especially through menopause, training both isn’t optional if the goal is staying genuinely, confidently independent for the long run.
You’re not training to shrink, and you’re not training only to lift heavier. You’re training to keep everything that lets you move through the world without thinking twice about it.
General information, not medical advice. If you have joint problems, balance concerns, or any medical condition, check with a qualified professional before starting new explosive movements.
