Quick answer
The 2023 International PCOS Guideline recommends that women with PCOS follow the general adult activity guidelines: 150 to 300 minutes of moderate-intensity activity a week, plus muscle strengthening on two days, and less time sitting. No single type of exercise has been shown to work better, so the guideline suggests choosing activity you enjoy and can keep up.
Tvarvi Key Takeaways
What the guideline says
- Some physical activity is better than none.
- Adults aim for 150 to 300 minutes of moderate-intensity activity a week.
- Add muscle strengthening on two days that are not back to back.
Choosing an activity
- No one type of exercise has been shown to be better than another.
- Walking, cycling, chores, sport and planned exercise all count.
- Pick something you enjoy and can keep doing.
Why it matters
- Activity helps metabolic health in PCOS.
- Healthy habits matter even when weight does not change.
- Sitting less is a goal of its own.

The 2023 International Evidence-based Guideline for PCOS recommends lifestyle intervention, meaning exercise alone or diet combined with exercise and behavioural strategies, for all women with PCOS to improve metabolic health, including waist measurements and blood fats (cholesterol).
The same guideline describes lifestyle management as a core focus in PCOS care, with goals co-developed in partnership with each woman and her preferences. The WHO fact sheet on PCOS also lists physical activity, together with healthy eating, as important for all women with PCOS.
For how weight, insulin and PCOS connect, read our main guide, PCOS and weight gain.
The PCOS guideline uses the same targets as the general adult guidelines. For adults aged 18 to 64, the 2023 guideline advises 150 to 300 minutes of moderate-intensity activity a week, or 75 to 150 minutes of vigorous-intensity activity, or a mix of both, spread through the week.
It also advises muscle-strengthening activities on 2 non-consecutive days a week, and says aerobic activity should be done in bouts of at least 10 minutes, aiming for at least 30 minutes daily on most days.
These numbers match the WHO 2020 guidelines on physical activity and sedentary behaviour, which recommend that all adults do 150 to 300 minutes of moderate-intensity or 75 to 150 minutes of vigorous-intensity activity a week, along with regular muscle-strengthening activity.
Table 1. Weekly activity targets in the 2023 PCOS guideline
| Who | Aerobic activity | Muscle strengthening |
|---|---|---|
| Adults aged 18 to 64 | 150 to 300 minutes moderate, or 75 to 150 minutes vigorous, a week | On 2 days that are not back to back |
| Adolescents | At least 60 minutes moderate to vigorous a day | At least 3 times a week |
Source: Teede et al., Recommendations from the 2023 International Evidence-based Guideline for the Assessment and Management of PCOS, J Clin Endocrinol Metab, 2023. Alt text: "Table of weekly physical activity targets for adults and adolescents from the international PCOS guideline."
If these targets feel far away, the WHO 2020 guidelines reaffirm that some physical activity is better than none.
Any activity counts, and the evidence does not favour one type. The 2023 guideline says there is a lack of evidence that any one type or intensity of exercise is better than another for body measurements, metabolic, hormonal, reproductive or psychological outcomes.
Because of that, the guideline advises sustainable physical activity based on each woman's preferences and goals. It defines physical activity broadly: leisure activity, walking or cycling to get somewhere, work, household chores, games, sport and planned exercise all count.
So a brisk walk, a dance class, a sport or a yoga session can all be part of your week. If you would like guidance on a yoga routine, you can talk to a yoga coach.
Exercise is linked with better insulin sensitivity in women with PCOS. A 2020 systematic review and meta-analysis by Patten and colleagues, covering 777 women in 19 meta-analysed studies, found that vigorous-intensity exercise led to a moderate rise in fitness and a small reduction in HOMA-IR, a measure of insulin resistance.
The same review concluded that its results support the use of exercise and found that the health gains depended more on how hard women exercised than on how much, while calling for longer studies.
The 2023 guideline recognises insulin resistance as a factor in PCOS, but says the insulin blood tests available in clinics are of limited value and should not be used in routine care. Read more in our guide to insulin resistance in women.
Yes. The 2023 guideline states that there are benefits to a healthy lifestyle even when weight does not change, and the WHO says healthy eating and physical activity are important for all women with PCOS whatever happens to their weight.
The guideline also recommends healthy lifestyle habits for all women with PCOS to improve general health and quality of life. It asks health professionals to be aware of weight stigma when they talk about lifestyle. A nutritionist can personalise eating habits around your routine.
Evidence on hormones is still limited. A 2019 Cochrane review of lifestyle changes in PCOS found that lifestyle intervention may improve the free androgen index, a measure of androgens (hormones such as testosterone), but rated the evidence as low quality, and found no studies that looked at menstrual regularity.
Sitting less is a separate goal from exercise. The 2023 guideline advises adults to limit time spent sitting and on screens, because replacing sitting time with activity of any intensity, including light activity, provides health benefits.
The WHO 2020 guidelines also recommend reducing sitting time (sedentary behaviour) for all age groups, while noting that the evidence was not enough to set a threshold for how much sitting is too much.
Tracking can help with this. The 2023 guideline says self-monitoring, including with fitness trackers for step count and exercise intensity, could be considered to support an active lifestyle and less sitting.
Many things can get in the way, and the guideline asks doctors to talk about them. The 2023 guideline lists barriers such as body image concerns, fear of injury or failure, mental health, personal safety, physical limitations, and social, cultural and money factors, and says the value of involving the wider family should be considered.
The guideline suggests behavioural strategies such as goal setting, self-monitoring, problem solving and SMART goals (specific, measurable, achievable, realistic and timely) to support a healthy lifestyle and emotional well-being.
Mood matters here too. The guideline says lifestyle intervention should be considered, along with other therapies that target PCOS features, given its potential to improve psychological symptoms. Our article on PCOS, anxiety and mood explains this link.
The 2023 guideline advises adolescents to aim for at least 60 minutes of moderate- to vigorous-intensity activity a day, including activities that strengthen muscle and bone at least 3 times a week.
For those who are not overweight, and for adolescents, the guideline says the focus should be on a healthy lifestyle and preventing excess weight gain. If you are a teenager with questions about PCOS, it helps to see a gynaecologist with a parent or guardian.
If you have a health condition or are unsure where to start, a gynaecologist can talk you through what fits your situation.
Does yoga count as exercise for PCOS? Yes. The 2023 International PCOS Guideline found no evidence that any one type of exercise works better than another, and advises activity that suits your own preferences, so yoga can be part of your week.
Do household chores count as exercise? Yes. The 2023 guideline defines physical activity as any bodily movement that uses energy, including household chores, walking or cycling to get somewhere, work and sport.
Is it better to exercise in one long session or several short ones? The 2023 guideline suggests aerobic activity in bouts of at least 10 minutes, aiming for at least 30 minutes on most days, spread through the week.
Should I check my insulin level before starting exercise? The 2023 guideline says the insulin blood tests available in clinics are of limited value and should not be used in routine care. A doctor can advise which checks fit your situation.
