The short explanation
Both cardio and strength training can help with PCOS, and combining them is often recommended. Cardio, such as brisk walking, cycling, dancing or swimming, helps heart health and burns energy. Strength training, such as weights, resistance bands or bodyweight exercises, builds muscle, which improves how the body uses insulin. The most important factor is doing something regularly that you enjoy and can keep up. Exercise can improve insulin resistance, mood and periods even without large weight loss. Many guidelines suggest building up to at least around 150 minutes of moderate activity spread across the week, plus strength exercises on a couple of days.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Starting slowly and increasing gradually helps avoid injury, especially if you have not exercised for a long time.
- Very intense exercise combined with eating too little can disturb periods, so balance matters.
- If you have heart, joint or other health problems, check with a doctor before starting a new exercise routine.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot give you a personal exercise plan. A doctor or trainer can help based on your fitness and health.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- What type of exercise would suit me with PCOS?
- How much should I aim for each week?
- Are there any health reasons I should be careful?
- How will I know if exercise is helping?
When to seek help

Whatever you choose is filed against this version of the answer, never against you, and it is never shown as a count.
“Explain more simply” asks you which part was hard to follow, so the author knows what to rewrite. “My question is different” opens a private follow-up with this answer attached.
