Intermediate Evidence: Strong evidence 3 min read Reviewed 2026-10-31 Status: draft

Learning objectives

  • Describe the features of PCOS
  • Explain links with insulin resistance and metabolic risk
  • Apply guideline exercise recommendations
  • Support clients with weight-neutral, sustainable approaches

Before this lesson

Why this matters

PCOS is one of the most common hormonal conditions in women of reproductive age.

Features

Irregular or absent ovulation, signs of high androgens (acne, excess hair growth) and/or polycystic ovaries on ultrasound. Insulin resistance is common.

Guideline recommendations [teede2023]

ComponentRecommendation
Aerobic150–300 min/week moderate or 75–150 min/week vigorous
Resistance2 non-consecutive days
SittingMinimise
ApproachSustainable, enjoyable, weight-neutral goals

Evidence

Exercise improves insulin resistance, fitness and body composition, with vigorous exercise possibly more effective [patten2020].

Common mistakes and misconceptions

Case study

A 27-year-old with PCOS combines three strength sessions and two interval sessions weekly. Her doctor reports improved insulin sensitivity after 4 months.

  • Insulin resistance is common, increasing metabolic risk.
  • The 2023 guideline recommends 150–300 min/week moderate or 75–150 min/week vigorous activity plus muscle strengthening.
