If you’ve got PCOS (polycystic ovary syndrome), you’ve probably had a doctor tell you to “just lose weight and exercise more.” Brilliant advice, that. Super helpful. About as useful as telling someone with depression to “cheer up,” really.
The frustrating thing about PCOS is that it makes losing weight harder, and yet weight loss is often recommended as one of the main treatments. It’s like being told to climb a mountain whilst someone keeps moving the summit further away. But here’s the thing: whilst exercise won’t “cure” PCOS (nothing will, because it’s not actually curable), the right type of exercise really can help manage symptoms.
So let’s talk about what actually works, what doesn’t, and how to exercise with PCOS without wanting to throw your trainers out the window.
A quick note before I go any further: I’m a blogger, not a doctor or endocrinologist. The guidance below is based on research I’ve read and my own experience — but your situation is individual, and anything that significantly affects your hormones is worth discussing with your GP or a specialist. Right, on with it.

What Is PCOS, Anyway?
Right, quick science bit. PCOS is a hormonal condition that affects how your ovaries work. It’s really common – about 1 in 10 women in the UK have it. The name is a bit misleading because you don’t actually need to have cysts on your ovaries to be diagnosed with it.
Common symptoms include:
- Irregular or absent periods
- Excess hair growth (face, chest, back)
- Difficulty losing weight or weight gain
- Thinning hair on your head
- Acne or oily skin
- Difficulty getting pregnant
- Insulin resistance (your body doesn’t respond well to insulin)
That last one – insulin resistance – is really important when it comes to exercise. Many women with PCOS have insulin resistance, which means their bodies produce more insulin to deal with blood sugar. This extra insulin can make it harder to lose weight and easier to gain it. It’s not fair, but it’s biology.
Why Exercise Helps With PCOS
Exercise can’t cure PCOS, but it can genuinely help with several symptoms. Here’s what the research actually shows:
Improves insulin sensitivity: This is probably the biggest benefit. Exercise helps your muscles use glucose more effectively, which means your body doesn’t need to produce as much insulin. Over time, this can really help manage PCOS symptoms.
Helps with weight management: Yes, losing weight with PCOS is harder, but it’s not impossible. Exercise, combined with the right nutrition, can help. And here’s the thing – even modest weight loss (around 5-10% of your body weight) can improve symptoms significantly.
Regulates periods: Regular exercise can help regulate your menstrual cycle. Not for everyone, but many women find their periods become more predictable when they’re consistently active.
Reduces inflammation: PCOS often comes with chronic low-grade inflammation. Exercise is anti-inflammatory, which can help reduce this.
Improves mood and energy: Let’s be real, PCOS can be bloody exhausting, both physically and mentally. Exercise releases endorphins and can genuinely help with fatigue and mood.
The Best Types of Exercise for PCOS
Now, here’s where it gets interesting. Not all exercise is created equal when you’ve got PCOS. What works brilliantly for one person might not work for you, but research does point to some types of exercise being particularly helpful.
Strength Training (Your New Best Friend)
If I had to recommend one type of exercise for PCOS, it would be strength training. No contest.
I started lifting weights properly a few years ago, partly for general fitness and partly because I kept reading that it was one of the best things you could do for hormonal health. The difference I noticed wasn’t dramatic and fast — it was gradual and then suddenly obvious. More energy. Less of that bone-deep fatigue that made afternoons difficult. Periods that were less all-over-the-place. I can’t tell you it’ll do the same for you because bodies are different, but I can tell you the research consistently backs this up.
Building muscle improves insulin sensitivity directly. Muscle tissue is metabolically active — it uses glucose for energy, which means your body doesn’t need to produce as much insulin to manage blood sugar. For PCOS, where insulin resistance is so often at the root of the problem, this matters.
What to do:
- Aim for 2-4 strength training sessions per week
- Focus on compound movements (squats, deadlifts, presses, rows)
- Start with weights you can manage and gradually increase
- Don’t be afraid to lift heavy – you won’t get “bulky,” I promise
You don’t need a fancy gym membership either. Bodyweight exercises, resistance bands, or a set of dumbbells at home will do the job perfectly well.
HIIT (But Not Too Much)
High-intensity interval training (HIIT) can be really effective for PCOS because it improves insulin sensitivity and cardiovascular fitness in less time than steady-state cardio. Studies show it can help reduce insulin resistance and improve body composition.
But – and this is important – too much HIIT can actually make things worse.
HIIT is stressful on your body (in a good way, usually), but if you’re already dealing with the stress of PCOS symptoms, hormonal imbalances, and possibly trying to juggle work and life as well, adding too much high-intensity exercise can increase cortisol levels. High cortisol can worsen PCOS symptoms and make weight loss even harder.
What to do:
- Limit HIIT to 1-2 sessions per week
- Keep sessions relatively short (20-30 minutes max)
- Make sure you’re recovering properly between sessions
- If you feel completely exhausted all the time, dial it back
Moderate-Intensity Cardio
Good old-fashioned moderate cardio – walking, cycling, swimming, dancing – shouldn’t be overlooked. It might not be as sexy as HIIT or strength training, but it’s brilliant for improving insulin sensitivity without overtaxing your body.
Walking, in particular, is massively underrated. A 30-minute brisk walk after meals can significantly help with blood sugar management. It’s low-stress, accessible, and you can do it every day without worrying about overtraining.
What to do:
- Aim for 150 minutes of moderate cardio per week (that’s the NHS recommendation)
- Walking, cycling, swimming, dancing – pick something you actually enjoy
- Consider walking after meals to help with blood sugar
- Don’t feel like you need to run marathons – consistency matters more than intensity
Yoga and Mindfulness Movement
Yoga won’t directly improve insulin resistance the way strength training will, but it can be incredibly helpful for managing the stress and mental health aspects of PCOS. Some research suggests that yoga can help reduce testosterone levels and improve menstrual regularity in women with PCOS.
Plus, if you’re dealing with chronic stress (which many women with PCOS are), yoga can help lower cortisol levels. High cortisol makes everything worse, so managing stress is crucial.
What to do:
- Include 1-2 yoga or stretching sessions per week
- Focus on styles that suit your energy levels (gentle yoga when you’re tired, more dynamic yoga when you feel good)
- Don’t underestimate the power of breathwork for stress management
What Doesn’t Work (Or Makes Things Worse)
Excessive Cardio
I know you’ve probably heard that you need to do loads of cardio to lose weight, but honestly, marathon cardio sessions aren’t the answer for PCOS. Hours on the treadmill or bike can increase cortisol, stress your body out, and potentially make insulin resistance worse.
If you love running, by all means keep running. But if you’re forcing yourself to do hour-long cardio sessions because you think you “should,” you might want to rethink that approach.
Over-Exercising
This is a big one. It’s tempting to think that more exercise equals better results, especially when you’re frustrated with slow progress. But with PCOS, over-exercising can backfire spectacularly.
Too much exercise increases inflammation, raises cortisol, suppresses your immune system, and can make hormonal imbalances worse. If you’re training hard every single day and still not seeing results, that might be your problem right there.
Signs you’re overdoing it:
- Constant fatigue that doesn’t improve with rest
- Sleep problems
- Getting ill frequently
- Worsening PCOS symptoms
- Periods stopping (if you had them)
- Obsessive thoughts about exercise
Rest days aren’t optional – they’re when your body actually adapts and gets stronger.
Fasted Cardio
There’s this idea that doing cardio first thing in the morning on an empty stomach will help you burn more fat. For women with PCOS and insulin resistance, this can actually be counterproductive.
Fasted exercise can increase cortisol and potentially worsen insulin sensitivity. If you prefer morning workouts, that’s fine, but having something small to eat beforehand (even just a banana or a bit of toast) is probably better for your hormones.
Creating Your PCOS-Friendly Exercise Routine
Right, so what does a good week of exercise look like for someone with PCOS? Here’s an example:
Monday: Strength training (full body, 45 minutes)
Tuesday: Moderate walk or yoga (30-45 minutes)
Wednesday: Strength training (upper body focus, 45 minutes)
Thursday: Rest day or gentle stretching
Friday: Strength training (lower body focus, 45 minutes)
Saturday: HIIT or moderate cardio (20-30 minutes)
Sunday: Long walk, yoga, or complete rest
This gives you 3 days of strength training, some cardio for heart health, stress management through yoga or walking, and proper rest days. You can absolutely adjust this based on your schedule and energy levels.
The Nutrition Connection
I know this post is about exercise, but I can’t talk about PCOS without mentioning nutrition briefly. Exercise and diet work together – you can’t out-exercise a diet that’s making your insulin resistance worse.
Focus on:
- Balanced meals with protein, healthy fats, and complex carbs
- Avoiding blood sugar spikes (pair carbs with protein or fat)
- Eating regularly rather than skipping meals
- Not cutting calories too drastically (this can worsen hormones)
I’ll save the full nutrition chat for another post, but just know that exercise alone isn’t the whole picture.
When Exercise Isn’t Helping
If you’re doing all the right things — lifting consistently, managing stress, not over-exercising — and still not seeing any improvement in symptoms, please go back to your GP. Not because you’ve done anything wrong, but because PCOS is a medical condition and exercise is one tool, not the whole toolkit.
Metformin is commonly prescribed for the insulin resistance side of things and can make a real difference. The combined pill can help regulate periods. Inositol supplements have reasonable evidence behind them for some people, though worth discussing with a doctor before starting. There’s more available than “just exercise more,” and you’re entitled to access it.
Don’t let anyone — including well-meaning fitness content — convince you that if you just work out hard enough and eat clean enough, you can manage PCOS on willpower alone. That’s not how it works.
The Bottom Line
Exercise really can help manage PCOS symptoms, but it needs to be the right type of exercise in the right amounts. Strength training should be your priority, moderate cardio is great for heart health and insulin sensitivity, and stress management through yoga or gentle movement is important too.
But more isn’t always better. Over-exercising can make PCOS worse, so listen to your body and give yourself proper rest.
Most importantly, be patient with yourself. PCOS makes everything a bit harder, including weight loss and fitness progress. That’s not your fault, and it doesn’t mean you’re doing anything wrong. Keep showing up, be consistent, and remember that even small improvements in symptoms are worth celebrating.
PCOS makes everything a bit harder, including fitness progress. That’s not a personal failing and it’s not you doing something wrong — it’s the condition. Keep showing up when you can, rest when you need to, and don’t compare your progress to people who don’t have the same hormonal headwinds.
And if your GP is still just telling you to “exercise more” without any further help — it’s completely reasonable to push back, ask for a referral, or seek a second opinion. You deserve more than that.
