Exercise and Menopause: What Evidence Shows

Let’s start with the bad news, the part no gym ad will give you: the evidence doesn’t consistently show that exercise gets rid of hot flashes or night sweats. If that’s why you came, better to know now than after paying for a six-month package.

The good news is longer, and it has to do with bone and muscle, which do respond. And they respond well.

Hot flashes: the part exercise doesn’t fix

The Cochrane review on exercise and vasomotor menopause symptoms (Daley and colleagues, 2014) pooled available data from several controlled trials, comparing exercise against doing nothing and against yoga. With low-quality evidence, they found no clear difference between exercising and not exercising in the frequency or intensity of hot flashes and night sweats.

This contradicts a fair amount of wellness-industry marketing, which promises that “moving” resolves vasomotor symptoms. It isn’t what the available evidence shows. If hot flashes are your main complaint, the conversation worth having is with your doctor: there are treatments, including hormone therapy, evaluated case by case based on your history. That’s not something a blog post or an exercise class resolves.

Where it does help: protecting bone

Here’s where the story changes. The Cochrane review on exercise for preventing and treating osteoporosis in postmenopausal women (Howe and colleagues, 2011) found that exercise has a protective effect, modest but real, on bone mineral density at the spine and hip, compared to doing nothing. That same analysis didn’t find sufficient evidence that, on its own, it reduces the number of fractures. It’s a distinction that matters: improving a marker isn’t the same as preventing the final outcome.

Bone density loss accelerates in the years around menopause because of falling estrogen, which is exactly the phenomenon behind that review. That exercise can counterbalance part of that process (even modestly, with no guarantee on fractures) is one of the few non-pharmacological tools with real evidence behind it.

Why impact and strength matter more in these years

Not every kind of exercise seems to carry the same weight for bone. The LIFTMOR trial (Watson and colleagues, 2018, published in the Journal of Bone and Mineral Research) compared, in postmenopausal women with low bone mass (osteopenia or osteoporosis), a supervised high-intensity strength and impact training program (heavy lifting and controlled jumps, twice a week for eight months) against a low-impact home program. The high-intensity group showed significantly greater improvements in bone mineral density at the lumbar spine and femoral neck. And a relevant detail for anyone afraid of lifting heavy at this stage: there were no serious injuries in any participant under proper supervision.

It’s a single trial, with close supervision built into the design. It’s not evidence to go jump around unguided if you have diagnosed low bone mass. But it is a strong signal that strength and well-dosed impact, not just gentle movement, is what seems to matter most for bone at this stage.

The other silent change: muscle mass

Alongside bone, muscle also starts to noticeably decline over the years: it’s the process the EWGSOP2 consensus (Cruz-Jentoft and colleagues, 2019, in Age and Ageing) describes as sarcopenia. It isn’t exclusive to menopause, but it overlaps with this decade, and the combination of less muscle and lower bone density is exactly what’s most associated with falls and fractures later on.

Strength training is, based on what’s published, a reasonable part of how that process is addressed. It’s not a promise to reverse it entirely. It does, however, have plenty of clinical logic to be a priority at this stage, not a secondary option.

The warning we can’t skip

If you have diagnosed osteoporosis (not suspicion, confirmed diagnosis), the step before any impact or high-load class is a medical evaluation. Not because exercise is inherently dangerous, but because the dose and type of load your body can safely tolerate depends on how compromised your bone density is, and that’s determined by a scan, not a group class. Tell your instructor before your first session, and bring any guidance your doctor gave you.

If you’re also in the conversation about hormone therapy, that’s a conversation with your doctor, with your full history on the table, not something this article, or any exercise class, can decide for you.

How this looks at Naü

In the studio, at Plaza Muray, the classes with the most strength and controlled-impact component are HIIT and Lab Funcional; Barre works strength with more isometric emphasis and less impact, a reasonable option if you’re starting out or prefer to progress before higher loads. They run 45 to 50 minutes. Tell your coach your situation before you begin. It’s the same as at any other life stage where the body changes the rules, like pregnancy and postpartum.

If you’ve never trained strength, or haven’t in years, you don’t need to start with the most intense option. Progressing from less to more, mastering the movement before adding load or impact, is just as valid at this stage as at any other. And that’s exactly what small groups are for: someone watching how you move before raising the demand.

FAQ

Does exercise get rid of menopause hot flashes?

The available evidence, a 2014 Cochrane review, found no clear difference between exercising and not exercising in the frequency or intensity of hot flashes. It’s not what exercise resolves best at this stage.

What kind of exercise helps bone the most during menopause?

What’s been published so far, including the LIFTMOR trial, points to strength training with higher loads and some controlled impact, under supervision, being associated with greater improvements in bone density than low-impact exercise alone.

I have diagnosed osteoporosis, can I take impact classes?

Talk to your doctor before any class with high load or impact, and share that evaluation with your instructor. The safe dose depends on exactly how compromised your bone density is.

At what age should I prioritize strength training for hormonal reasons?

There’s no exact cutoff age. Bone density loss accelerates around menopause, so training strength before reaching that stage, and keeping it up during and after, is what the research supports so far.

Can I start strength training if I’ve never done it?

Yes, and you don’t need to start with the most intense option. Progressing from less to more, with someone watching how you move before raising the load, is just as valid at this stage as at any other.
