Strength Training in Perimenopause: What Actually Changes

You didn’t do anything differently. Same training, same effort, roughly the same life. But something shifted. The weights that felt fine last year feel heavier now. You’re more sore, for longer. Sleep is patchier. And your body seems to be keeping a little more around the middle no matter what you do.If that’s you, you’re not imagining it, and you’re not doing it wrong. This is perimenopause — the years-long lead-up to menopause that usually starts somewhere in your forties, though it can begin earlier. And it changes how your body responds to training in ways nobody really warns you about.The good news is that strength training isn’t the thing making it harder. It’s the thing that helps most.## What’s actually happeningPerimenopause isn’t a switch that flips. It’s a gradual, often bumpy decline in estrogen, with plenty of ups and downs along the way. And estrogen does more than most of us were ever taught — it plays a role in maintaining muscle and protecting bone. So as it declines, both of those get harder to hold onto.That’s the honest picture behind what you’re feeling:- **Muscle** becomes harder to build and easier to lose, which affects strength, metabolism, and how you feel day to day.
– **Bone density** starts to drop more quickly, which is why this window matters so much for long-term health.
– **Recovery** slows down — the soreness lingers, and the sessions you used to bounce back from take a little more out of you.
– **Body composition** shifts, often toward more storage around the middle, even when nothing else has changed.None of this is a personal failing. It’s physiology. And once you know what you’re working with, you can train in a way that works *with* your body instead of against it.## Why strength training becomes your best toolHere’s the part fitness culture usually gets backwards. When the body composition changes show up, the standard advice is to do more cardio and eat less. For a lot of women in perimenopause, that combination makes things worse — more fatigue, more muscle loss, more frustration.Strength training is the underused lever. It’s one of the most direct ways to hold onto muscle when your body is trying to let it go. It supports bone, which matters more now than it ever has. It helps with how your body handles blood sugar and energy. And for many women, it does something quieter but just as real — it gives back a sense of capability in a season where a lot feels out of your control.You don’t need to train harder than you used to. You need to train in a way that protects what matters: your strength, your bones, and your energy for the rest of your life.## What changes about how you trainYou don’t throw out everything you know. But a few things are worth adjusting:**Lift with intention.** This is not the season for endless light reps. Challenging your muscles with meaningful resistance is what signals your body to keep the muscle and bone it’s tempted to shed. Heavier, controlled, and well-supported beats frantic and light.**Respect recovery more than you used to.** If a session takes more out of you now, that’s information, not weakness. More rest between hard sessions isn’t going soft — it’s how you keep making progress when recovery is slower.**Protein matters more.** Your body holds onto muscle less easily now, so giving it enough to work with becomes more important than it was in your thirties.**Stop punishing yourself with cardio.** Movement you enjoy is wonderful. But grinding through more and more cardio to “fix” body composition usually backfires here. Strength first.## And then there’s real lifeOf course, all of this assumes you have the time, energy, and headspace to train perfectly. Most of us don’t.Perimenopause rarely arrives on its own. It tends to show up in the middle of everything else — older kids, aging parents, a demanding job, a household that doesn’t run itself. Some weeks you’ll train three times. Some weeks you’ll manage one session in your kitchen before everyone wakes up. Both count.That’s the whole point. Real strength in this season isn’t built in perfect conditions. It’s built in the gaps, on the ordinary days, in the middle of a full life. The women who keep going aren’t the ones with the most time. They’re the ones who let “something” count when “ideal” isn’t on offer.## Where to startIf this is landing and you’re not sure what to do with it, start small:- Two strength sessions a week is enough to begin. You don’t need four.
– Pick a handful of movements you can actually do at home or in a gym — a squat, a hinge, a push, a pull — and get stronger at them over time.
– Prioritise protein at breakfast, since that’s the meal most of us under-do.
– Treat sleep and recovery as part of the training, not a break from it.You don’t need to overhaul your life. You need a way of training that fits the life you already have — and that keeps you strong through this phase and well beyond it.—*Perimenopause is one of the phases I write about in my book, **Strength Through the Messy & Beyond** — a real-life guide to strength training from preconception through perimenopause.
