Women's Health Truth Month · Week 2
Perimenopause
Isn't the End
of Your Strength.
It's the reason to start. The research on what strength training actually does during the menopause transition — and how to train through it.
Somewhere around your early-to-mid forties, something shifts. Maybe sleep gets weird. Maybe you're waking up at 3am drenched, or your joints ache in a way they didn't before. Maybe the workouts that used to leave you feeling great now leave you wiped out for two days. And then someone tells you: "Welcome to perimenopause. It's all downhill from here."
I want to lovingly but firmly push back on that.
Perimenopause is real. The changes are real. But "downhill from here" is not the truth. The truth is that this season is one of the most powerful times in your life to start lifting, and the research backs that up. Last week we talked about how women have been largely missing from exercise science research. This week we're going deeper into what the research we do have actually says about perimenopause, training, and your body's capacity to get stronger through all of it.
The physiologyWhat's Actually Happening in Perimenopause
Perimenopause is the transition leading up to menopause, defined as your final period. It can last anywhere from a few years to a decade, and for many women it starts in their early-to-mid forties, sometimes earlier. It's not a single event. It's a season.
During this time, estrogen doesn't just slowly fade. It swings, sometimes dramatically, up and down before it settles lower. Progesterone also declines. And because these hormones do a lot more than govern reproduction, the effects show up all over the body.
Last week we talked about how estrogen helps protect your bones and muscle. So when estrogen swings and then settles lower, those systems feel it. Bone loss tends to accelerate around the menopause transition. Muscle becomes harder to hold onto without a strong reason to keep it. Sleep, mood, and recovery can all get disrupted. Joints can ache. Energy can be unpredictable.
None of that is a character flaw. It's physiology. And physiology responds to training.
The evidenceWhat the Research Actually Shows
Here's what I want every woman in perimenopause to know. Your body still responds. The door has not closed. And we have real data to show it.
In this trial, postmenopausal women with low bone mass — osteopenia and osteoporosis, the women most people would tell to "be careful" — did supervised, high-intensity strength and impact training twice a week, for just 30 minutes. They lifted heavy: 5 sets of 5 reps at over 85% of their max.
After 8 months, their lumbar spine bone density went up about 2.9%. The low-intensity home exercise control group? Lost about 1.2%. The strength training group also improved on every physical function test. There was one minor adverse event (a back spasm) in the entire training group.
Women with low bone density. Lifting heavy. Getting stronger bones. Let that rewrite whatever you've been told about what you're allowed to do.
A randomized trial out of Sweden put postmenopausal women with frequent moderate-to-severe hot flashes on a 15-week strength program, three days a week. Their hot flash frequency dropped by about 44%. The control group? About 2%.
That's one trial, and it's not a cure-all. But for a symptom most women are told to simply ride out, a 44% reduction from something you have direct control over is worth knowing about.
The Study of Women's Health Across the Nation (SWAN) followed women through the menopause transition long-term. Women who increased their physical activity, even modestly, saw slower bone loss at the hip compared to those who didn't.
You don't have to go from zero to powerlifter. The body is responsive. Every bit counts, and every bit compounds over time.
In practiceHow I Coach Women Through Perimenopause
This is where the evidence gets practical. I don't train women in perimenopause the exact same way I'd train a 25-year-old. But I don't train them like they're fragile, either. The goal is smart, progressive, sustainable training that gets more specific as their body shifts.
If your body can't recover from the workout you're giving it, the workout needs to change, not you. Debilitating soreness that lasts two or three days is a signal to scale back, not push harder. Over time, as your body adapts, that response changes. We adjust accordingly.
Your bones and muscles respond to load, not to going through the motions. "Light weights, high reps" is not going to send the signal your skeleton needs. We build up carefully, with good form and smart progression, but we build up. The LIFTMOR data isn't an outlier. It's the direction.
Moving with intent and some speed, think stepping up quickly, getting up off the floor with purpose, controlled jumps when you're ready, trains the fast-twitch muscle fiber that declines faster with age than slow-twitch. That's fall prevention. It's why we spend time in a power cycle each year, and it matters more as you get older, not less.
Some days you'll feel amazing. Some days you'll feel like a truck hit you. Both days tell us something. The goal isn't to perform the same way every session. It's to build the self-awareness to adjust as your body shifts, instead of fighting it or quitting because of it.
Protein matters even more in perimenopause. Muscle protein synthesis becomes less efficient as estrogen declines, which means you need more protein input to get the same muscle-building signal. If you're not sure where to start, add 20 to 30 grams a day to what you're already eating. Prioritize sleep the best you can. Drink your water. These aren't bonus points. They're part of the training.
Strength training isn't a replacement for working with a provider who takes menopause seriously. If your symptoms are disrupting your sleep, your relationships, or your ability to function, that is worth a conversation with someone who knows this territory. Hormone therapy, when appropriate, is an evidence-based option, and it works right alongside strength training, not instead of it. Whatever you and your provider decide, the training still matters. It still helps.
The real pictureWhat I See in My Classes
Building strength isn't fast. It takes time and grit, and in this season of life, it also takes grace. You're learning a new skill in a body that's changing underneath you. Some days you'll miss a lift. Some days your energy will be unpredictable and the session will feel hard for reasons that have nothing to do with fitness. That's not a verdict. That's a data point.
But here's what I actually see, over and over, in the women I train: women in their forties and fifties who are stronger now than they were at thirty. Women who can carry all the groceries in one trip again. Women who stopped being afraid of the stairs. Women who sat on the floor with their grandkids and got back up without thinking about it.
They didn't do it by training around perimenopause. They did it by training through it, with a program that was built for a woman's body in that season, with a coach who understood what was actually happening and didn't treat it as a reason to hold back.
Perimenopause isn't the end of your strength. For a lot of women, it's the beginning.
Next week we're going even further into the practical side: nutrition, protein targets, and how to eat in a way that supports the training you're putting in. Stick around.
I'm proud of you for learning about your body. You got this. Drink your water, eat your protein, get your steps in.
See y'all,
Amy, Refinery Strength Collective
