Vigorous aerobic exercise improves body composition, cardiorespiratory fitness, and insulin resistance in women with PCOS, whereas resistance training and combined aerobic-resistance interventions show inconsistent or no significant benefits on these specific metabolic markers.

For PCOS management, prioritize vigorous aerobic exercise (like brisk walking, cycling, or swimming) for at least 75-150 minutes per week. This specific modality has the strongest evidence for improving insulin resistance and body composition. Resistance training alone may not provide the same metabolic benefits, so use it as a supplement, not a replacement, for aerobic activity.

GoodQualifiesHIGH confidence
promising evidence supports the provision of vigorous aerobic exercise, which has been shown to improve body composition, cardiorespiratory fitness and insulin resistance.
