She had been running five days a week for years. Then perimenopause hit — and suddenly the weight was not shifting, her joints ached, and she was more exhausted after exercise than before. Sound familiar? The exercise rules change during perimenopause — and what worked in your 30s may actually be working against you now.
Why Exercise Is Non-Negotiable During Perimenopause
Regular exercise during perimenopause reduces hot flush frequency, improves sleep, protects bone density, maintains muscle mass, supports cardiovascular health, reduces anxiety and depression, and helps manage weight. No single medication or supplement comes close to matching these benefits.
Strength Training: The Most Important Exercise You Are Probably Not Doing Enough Of
If you do only one thing differently during perimenopause, make it strength training. After 40, women lose approximately 1% of muscle mass per year — a process that accelerates significantly during perimenopause. Muscle is metabolically active tissue that burns calories at rest, supports joints, protects bones, and improves insulin sensitivity.
💡 💡 Research finding: Women who do resistance training 2–3 times per week during perimenopause have significantly better body composition, bone density, and metabolic health than those who do cardio alone.
The Problem With Too Much Cardio
Chronic high-intensity cardio (daily long runs, spin classes every day) can actually worsen perimenopause symptoms by elevating cortisol — the stress hormone. High cortisol suppresses oestrogen, disrupts sleep, drives abdominal fat storage, and increases inflammation. This does not mean avoiding cardio — it means being strategic about it.
The Ideal Perimenopause Exercise Plan
- 1Strength training — 2–3 sessions per week, progressively increasing load
- 2Zone 2 cardio — moderate-intensity steady-state cardio (walking, cycling, swimming) 2–3 times per week
- 3High-intensity intervals — 1–2 short HIIT sessions per week maximum
- 4Yoga or Pilates — supports flexibility, core strength, and stress reduction
- 5Daily walking — 7,000–10,000 steps per day is independently associated with reduced hot flush severity
Exercise and Bone Health
Weight-bearing exercise (walking, running, dancing, strength training) is essential for maintaining bone density during perimenopause. Impact activities stimulate bone formation. Swimming and cycling, while excellent for cardiovascular health, do not provide the same bone-protective benefits.
