Exercise During Perimenopause and Menopause: Why What Worked Before Isn't Working Now (And What To Do Instead)

29 June

If you're exercising consistently but not seeing the results you used to — or if you've noticed menopause weight gain that doesn't respond the way it used to — you're not doing it wrong. Your body has changed what it needs from movement. Here's what actually matters during perimenopause and menopause — and why even starting small makes a real difference.

For most of my adult life, exercise wasn't really part of my world.

Not because I was unhealthy — I just didn't see the point for me personally. Gyms felt like places women went to lose weight. I didn't want to lose weight. So I didn't go.

Fitness culture talked about toning, burning, summer bodies. None of that spoke to me. So I lived my life without it.

Then I started strength training with a PT for a few years — not because I suddenly understood the science, but because it felt good. Only years later did I understand what I'd actually been doing. And by then I had already stopped and gone back to my "I don't do the gym" attitude.

Muscle isn't aesthetic. It's insurance. It protects your metabolism, your bones, your hormones, and your long-term independence. If someone had told me that when I was young, I would have started sooner — and I would have continued.

The good news is that it's never too late to start. During perimenopause and menopause, movement matters more than it ever has — and even one resistance training session a week is more than nothing. It makes a difference. From there, you build.

Why exercise during perimenopause and menopause works differently

Oestrogen doesn't just affect your periods or your temperature. It plays a role in muscle maintenance, bone density, joint health, and insulin sensitivity — and in how your body responds to and recovers from exercise.

As oestrogen fluctuates during perimenopause and declines in menopause, several things change:

Muscle becomes harder to build and maintain — research suggests this is related to changes in how muscle protein synthesis responds to training stimulus, though the exact mechanisms are still being studied
Bone density begins to decline more rapidly — resistance exercise becomes more protective than ever
Joints can become less resilient and more prone to inflammation — recovery from exercise may take longer
Insulin sensitivity often decreases — which is one of the key drivers of menopause weight gain, and changes how the body responds to different types of training and how it uses fuel
The body's stress response becomes more reactive — which is one reason that training load and recovery need more careful balancing than before

None of this means exercise matters less. It means the type, balance, and consistency of exercise matter more — and that getting it right pays off more than ever.

Why the old approach stops working

A common pattern: a woman who has always exercised consistently — running, cycling, gym classes — finds that the same routine is producing different results. Or no results. Or she's feeling more fatigued rather than energised.

This is not failure. It's physiology.

When oestrogen is lower, the same training load can feel harder on the body and take longer to recover from. The body's ability to adapt to exercise stimulus changes — not dramatically, but enough to matter. What worked well at 35 may need adjusting at 45 or 50.

This is one of the most common frustrations I hear from women who come to coaching: they're doing more than ever and feeling worse. The answer isn't to push harder. It's to train smarter — which means understanding what your body needs now, not what it needed a decade ago.

How hormonal changes affect body composition and energy is covered in more detail in the post on perimenopause and menopause weight gain — worth reading alongside this one.

Strength training: the foundation

If there is one form of exercise that earns its place unambiguously during perimenopause and menopause, it is resistance training. Not because everything else is wrong — it isn't — but because the benefits during this transition are specific, significant, and hard to replicate any other way.

It directly improves insulin sensitivity

This is the most important reason, and the most under-discussed. Reduced insulin sensitivity is one of the central changes of this hormonal transition — it affects energy, weight, and how your body uses food. Resistance training improves insulin sensitivity directly, which means it works on one of the root mechanisms, not just the symptoms.

It protects muscle mass

As oestrogen declines, maintaining muscle requires more deliberate effort. Resistance training — progressive, consistent, challenging enough to create a stimulus — is the most effective tool available for preserving it. This matters not just for how you look and feel now, but for strength, mobility, and independence in later life.

It supports bone density

Bone density declines more rapidly in the years around menopause. Resistance exercise is one of the most evidence-supported interventions for slowing that decline and reducing fracture risk in later life.

It changes body composition

Even when the number on the scale doesn't shift, resistance training changes the ratio of muscle to fat. For women experiencing menopause weight gain, particularly the shift toward more fat around the abdomen, this is significant. Clothes fit differently. Strength increases. Body composition improves — even without weight loss.

A note on metabolism

You may have read that building muscle boosts your metabolism significantly. This is technically true but often overstated. The actual difference in resting calorie burn between more and less muscular bodies is smaller than it's frequently made out to be — and current research suggests resting metabolic rate doesn't decline significantly until we're well into our 60s.

The stronger case for resistance training is insulin sensitivity, muscle preservation, and body composition — not a dramatic metabolic lift. It's genuinely valuable; it just works differently than the marketing suggests.

How much, and how often?

Two to three sessions per week of progressive resistance training is a solid foundation for most women during this transition. Sessions don't need to be long — 40 to 50 minutes is enough.

'Progressive' is the key word. The body adapts to the same stimulus. To keep seeing results, the challenge needs to increase over time — more weight, more reps, or more complexity. This is where working with a trainer at least initially makes a real difference.

And if two to three sessions a week feels out of reach right now, start with one. One session a week is not nothing. It is the beginning — and the body responds to it.

Cardio, HIIT, and how they fit together

Cardiovascular exercise matters — for heart health, mood, energy, and overall fitness. It's not something to deprioritise during perimenopause and menopause. But it works best as part of a broader plan rather than as the main event.

All forms of moderate cardio — walking, running, cycling, swimming, dancing — improve cardiovascular health, support mood, and contribute to overall fitness. There's no hierarchy here. The best cardio is the kind you'll actually do consistently.

Walking in particular is worth highlighting. Brisk walking is one of the most underrated forms of exercise during this transition. It supports cardiovascular health, improves recovery between harder sessions, and is easy to build into a day without needing to carve out gym time.

HIIT: why it belongs in your routine

High-intensity interval training has a reputation for being hard on the body during menopause. Used well, the opposite is true — HIIT is one of the most effective forms of exercise for women in perimenopause and menopause.

Here's why it matters:

HIIT improves cardiovascular fitness efficiently — short bursts of effort followed by recovery produce significant cardiovascular adaptations in less time than steady-state cardio
It stimulates muscle preservation — the intensity of effort creates a stronger training stimulus than moderate-pace cardio
It improves insulin sensitivity — high-intensity effort is particularly effective at improving how muscles take up glucose
It supports bone density — impact and intensity both contribute to bone stimulus

The important distinction is not whether to do HIIT — it's how often. Daily HIIT, or back-to-back intense sessions without adequate recovery, asks more of the body than it can deliver during this transition. The sweet spot is one to two HIIT sessions per week, with recovery built in around them.

If you've been avoiding HIIT entirely because you've heard it's bad for hormones, it's worth reconsidering. The issue isn't the intensity — it's the volume and the recovery. Get those right and HIIT earns its place firmly in the plan.

A practical weekly balance

For most women during this transition, a well-structured week might look like:

Two to three resistance training sessions as the foundation
One to two HIIT sessions for cardiovascular intensity and muscle stimulus
Regular moderate cardio — walking, a run, a class — on other days
Rest or active recovery (light movement, stretching) built into the week

If you've been doing mostly cardio and wondering why results have plateaued or why menopause weight gain isn't shifting despite consistent effort, the shift worth making is adding resistance training and some structured intensity — not doing more of what's already not working.

Movement beyond the gym

The research on NEAT — Non-Exercise Activity Thermogenesis, the energy used through everyday movement outside formal exercise — is clear: it matters a great deal.

Walking to meetings rather than driving. Taking the stairs. Standing rather than sitting. A short walk after meals. These aren't trivial. Across a day, they add up significantly — and they support insulin sensitivity and blood sugar stability in a way that one gym session doesn't fully compensate for.

For women during perimenopause and menopause, maintaining a generally active baseline throughout the day is at least as important as what happens in a formal workout. This is particularly useful for anyone who can't get to the gym consistently — movement doesn't have to be formal to count.

Recovery: why it's part of the plan

Recovery is not optional. During perimenopause and menopause, it becomes a non-negotiable part of any exercise plan — not something to fit in if there's time, but something to plan for deliberately.

When oestrogen is lower, the body's ability to bounce back from training effort changes. Training harder or more frequently doesn't produce proportionally better results — it produces slower recovery, disrupted sleep, and often a sense of working hard without getting anywhere.

Signs that your training load may be outpacing your recovery:

Persistent fatigue that exercise doesn't resolve
Sleep getting worse despite being physically tired
Feeling more anxious or irritable around heavy training days
Performance declining despite consistent effort
Increased cravings, particularly for carbohydrates and sugar

If any of these sound familiar, the answer is rarely to do more. It's to rebalance — making sure rest days are genuinely restful, sleep is prioritised, and the overall training load matches what your body can currently absorb and adapt to.

This is also where breathwork has a direct role. Breathing techniques based on Buteyko and Oxygen Advantage approaches support nervous system regulation and recovery — not as a replacement for rest, but as a practical tool for helping the body shift into a state where recovery can actually happen. It's something I work on with clients specifically, and the difference it makes between and after sessions is real.

How nutrition and exercise connect

Exercise during perimenopause and menopause works best as part of a broader picture — and nutrition is the piece it connects to most directly.

A few things worth knowing:

Protein supports muscle building and repair — without adequate protein, resistance training produces less result. What matters most is that you're eating enough protein consistently across the day; meal timing around training is worth experimenting with, but comes second to simply getting enough
Under-eating counteracts the benefits of training — severe calorie restriction combined with exercise stresses the body and accelerates muscle loss. More food, better quality, is usually the answer — not less
Blood sugar stability affects energy during exercise — carbohydrates eaten alongside protein and fat before a session tend to produce steadier energy than high-carbohydrate foods alone

The post on what to eat during perimenopause and menopause covers the nutrition side in detail, including protein targets, fibre, and the insulin sensitivity piece — worth reading alongside this one.

When to consider a menopause coach for exercise support

Exercise advice is everywhere. But knowing how to structure training for where you are specifically — your symptoms, your history, your energy — is a different thing.

It might be worth getting personalised support if:

You've been exercising consistently and not seeing results — or feeling worse rather than better
You're not sure how to balance strength, intensity, and recovery for your body right now
Fatigue is making it hard to train consistently
Exercise is one piece of a bigger picture that includes weight, sleep, and energy

As a perimenopause and menopause coach, I look at exercise as part of the whole picture — alongside nutrition, sleep, stress, and nervous system regulation — because none of these things work in isolation. Getting the combination right tends to produce results that changing one thing alone doesn't.

What to do if this sounds like you

Start somewhere — if you're not exercising at all, even one resistance training session a week is a meaningful starting point. Don't wait until you can do the full programme. Start with what's possible.
Build strength as your foundation — two to three sessions per week of progressive resistance training is the most impactful single change you can make to how you feel and how your body responds during this transition.
Add intensity with HIIT — one to two sessions per week of high-intensity work, with recovery built around it. Not daily, but not avoided either.
Keep moving throughout the day — the baseline of everyday movement matters as much as what happens in formal workouts.
Prioritise recovery as much as training — sleep, rest days, and nervous system support are part of the plan, not afterthoughts.
Match your nutrition to your training — particularly protein. Exercise without adequate nutrition produces less of the result you're working towards.

Frequently asked questions

What is the best exercise during perimenopause and menopause?

A combination of resistance training and HIIT is the most effective foundation, with regular cardio and daily movement alongside it. Resistance training builds and preserves muscle, improves insulin sensitivity, and supports bone density. HIIT provides cardiovascular intensity and further improves insulin sensitivity. The key is balance — not any single type of exercise done exclusively.

Is HIIT good or bad during perimenopause and menopause?

HIIT is good — and when used correctly, it's one of the most valuable forms of exercise during this transition. The issue isn't the intensity; it's the frequency. One to two HIIT sessions per week with adequate recovery around them is effective and appropriate. Daily HIIT without enough recovery is where problems tend to arise. If you've been avoiding it entirely, it's worth bringing back in.

Why is my exercise not working anymore during perimenopause?

Several changes affect how the body responds to exercise during perimenopause and menopause: reduced insulin sensitivity, changes in how muscle responds to training stimulus, and a reduced capacity to recover quickly from high training loads. The approach that worked well before may need adjusting — not abandoning. Adding resistance training, including structured intensity, and building in more recovery tends to shift things.

Should I do cardio or weights during menopause?

Both — but with resistance training as the foundation rather than cardio. Weights and HIIT together address the most important changes of this transition: insulin sensitivity, muscle preservation, and bone density. Cardio supports heart health and mood and absolutely has a place — it just shouldn't be the only thing, or even the main thing.

How often should I exercise during perimenopause and menopause?

A solid week might include: two to three resistance training sessions, one to two HIIT sessions, and regular moderate movement (walking, cycling, a class) on other days — with at least one proper rest day. Recovery is as important as the training itself. Starting from nothing? Begin with one resistance session and build from there. Consistency over months matters far more than volume in any single week.

Does exercise help with menopausal weight gain?

Yes — particularly resistance training and HIIT, which both improve insulin sensitivity directly. This matters because reduced insulin sensitivity is one of the key drivers of weight changes during this transition. Exercise works best alongside nutrition adjustments rather than in isolation.

Do I need a personal trainer for exercise during menopause?

Not necessarily, but starting with some guidance — particularly for resistance training — makes a real difference. Learning to train progressively and safely reduces injury risk and produces better results. Even a few sessions with a trainer to establish form and structure is worthwhile if it's accessible.
