HRT and Exercise: What to Expect When You Train

"Carrie, I've just started HRT… should I still be training? And is it going to make me put on weight?"

I get some version of that question almost every week. So if it's been on your mind, you're in very good company.

Here's the short, honest answer before anything else. Whether or not HRT is right for you is a decision for you and your GP, not for me. I'm a coach, not a doctor, and I'd never pretend otherwise. But the bit I do know inside out, after 7 years of helping women over 30 here in Southampton, is what happens when women train through this stage of life. And HRT and exercise? They make a brilliant pairing.

So let me walk you through it, the way I would if you were sat across from me with a cup of tea.

A quick, honest starting point

Let's get the most important thing out of the way first.

HRT is a personal, medical decision. It's something you weigh up with your GP, who knows your history, your symptoms and what's right for your body. Nothing in this article is medical advice, and nothing here is me telling you to start it, stop it, or change it.

What I can tell you about is the other half of the picture. Movement. Strength. How your body responds when you start training in a way that actually suits midlife. Because for a lot of women, HRT and exercise aren't an either/or. They're two things that work alongside each other.

Think of it this way. HRT, where your GP feels it's right for you, can help settle the symptoms that make everything harder: the broken sleep, the hot flushes, the low mood, the aching joints. Training builds the strength, the muscle and the confidence underneath. One helps you feel more like yourself. The other helps you stay strong and capable for the long haul. They complement each other beautifully.

What training never does is replace your medical care. It sits alongside it.

Does HRT cause weight gain?

This is the worry I hear most. So let's talk about it honestly, with no scare stories and no big promises.

The truthful answer is: it's nuanced, and it's individual. Some women worry HRT will pile weight on. Others find it actually helps them feel well enough to get moving again. The honest position is that this is something to talk through with your GP, who can speak to your situation. I genuinely can't tell you HRT will or won't change your weight, because that isn't mine to say, and it's different for every woman.

But here's what I can offer some reassurance on.

A lot of the changes women blame on HRT are actually the changes of midlife itself, happening at the same time. Oestrogen shifts in perimenopause and menopause, and that tends to move where the body stores fat, often onto the tummy. Muscle slowly declines with age, which nudges the metabolism down. It can be easy to start HRT and assume any change is the HRT, when a lot of it is simply the season of life you're in. I wrote about the bigger picture in my guide to menopause weight gain and how to lose it after 40, if you want the full story.

And the part that should genuinely take some weight off your shoulders: the things that protect your body composition through this stage are the same whether you're on HRT or not. Strength training. Enough protein. Decent sleep. Daily walking. None of that changes. So you are never powerless here, whatever you and your GP decide about HRT.

The "HRT and weight gain" worry keeps a lot of women stuck and scared. But the things that actually protect your shape and strength are in your hands, on HRT or off it.

How training and HRT work together

Here's where it gets genuinely encouraging.

When the worst of the symptoms ease off, whether that's through HRT, through training, or through both, life gets a little roomier. Better sleep means more energy for a session. Less joint ache means lifting feels kinder. Steadier mood means you actually want to turn up.

And training gives back in the places that matter most in midlife:

• Muscle and metabolism. Strength training rebuilds the muscle that quietly drifts away after 40, and muscle is what keeps your metabolism ticking over. It's the single biggest lever you have. I've gone deep on this in my guide to strength training for women over 40.
• Bones. Bone density tends to drop around menopause, and lifting and weight-bearing movement is one of the best things going for keeping them strong.
• Mood and energy. Movement is brilliant for how you feel, not just how you look. So many women tell me training is the thing that gives them their spark back.

None of that competes with HRT. It works right alongside it. If you're still in the earlier stages and finding your feet, my guide to exercise in perimenopause is a gentle place to start.

What to expect when you train

So what does training actually feel like through this season? Let me be straight with you, because honesty matters more than hype.

Some days will feel brilliant. Some days, especially while your symptoms or your HRT are still settling, you'll feel flatter, more tired, a bit off. That's completely normal, and it is not a sign you're doing anything wrong. Bodies in midlife have wobblier days. The answer isn't to flog yourself harder. It's to show up, do what you can, and trust the consistency.

A few honest expectations:

• Progress can feel less linear. Strength still builds, it just doesn't always march up in a straight line. Zoom out over months, not days.
• Recovery matters more. Sleep, rest days and protein do a lot of the quiet work. Pushing through exhaustion rarely pays off at this age.
• You won't "bulk up". Building serious muscle is slow and hard even when you're trying. What you'll build is leaner, stronger and far more capable.
• It's never too late to start. Honestly. Some of the biggest changes I see are in women who hadn't trained in years.

Rachel is the example I always come back to. She lost around 28kg and, more than that, got her confidence back, the bit no set of scales ever shows you. And Vanessa, a busy mum of two who runs her own business, trains around a packed life and now back-squats 70kg. She didn't live in the gym. She just kept turning up. That's the real secret, on HRT or off it.

If the thought of starting makes you want to hide, that's completely normal too. It's exactly why we train in small groups of women only. You will not be the odd one out.

You, your GP, and your training

Here's the honest bit to finish on.

Anything to do with HRT, your dose, your symptoms, your health history, belongs with your GP. They're the ones who can look at the whole picture and help you make the right call for you. Please don't take medical decisions from a fitness website, mine included. If you're starting or changing HRT and you're not sure how it fits with exercise, that's a perfect thing to ask them about, and it's worth a quick word before you ramp up your training too.

My job is the other half. Helping you train in a way that's safe, sustainable and actually enjoyable, so that whatever you and your GP decide, your body gets stronger and your confidence comes back.

That's exactly why I built Mindset. Small groups of women, training in a room where they finally feel like they belong, with someone in their corner making sure the plan fits real life, and real bodies, in real midlife.

Because the hardest part was never the training. It's making that first decision to do something different. Do that, and the rest follows. 💜

Quick honest note: this is general guidance from a coach, written to help you feel informed, not medical advice. HRT is a personal decision between you and your GP, and only they can advise on whether it's right for you, what it might do, and how it fits with exercise. If you've got health concerns, or you're thinking about starting, stopping or changing HRT, please speak to your GP first. Training is here to complement your medical care, never to replace it.
