Why Strength Training is the Best Thing You Can Do in Menopause
Most women are told to do more cardio when they hit perimenopause. Here's why that's the wrong advice — and what the research actually says.
If you've been slogging away at cardio and wondering why you're exhausted, gaining weight around your middle, and feeling worse than ever — you're not alone. And you're not doing anything wrong. You've just been given the wrong advice.
The Cardio Trap
For decades, women have been told that cardio is the answer: run more, cycle more, do more aerobics. But during perimenopause and menopause, this advice backfires. Here's why.
When oestrogen declines, your body becomes more cortisol-sensitive. Prolonged cardio spikes cortisol — the stress hormone — which in turn:
- Breaks down muscle tissue
- Increases fat storage around the abdomen
- Disrupts sleep
- Worsens mood and anxiety
The harder you work in the wrong way, the harder your body fights back.
What the Research Actually Shows
A growing body of evidence points to resistance training as the most effective intervention for menopausal symptoms. Here's what it does:
Preserves lean muscle mass. We lose 3–8% of muscle per decade after 30, and that accelerates in menopause. Strength training is the only proven way to slow and reverse this.
Protects bone density. Oestrogen plays a key role in bone health. As it declines, fracture risk rises sharply. Weight-bearing resistance exercise stimulates bone formation — it's the most evidence-backed non-pharmaceutical intervention available.
Improves insulin sensitivity. Muscle is metabolically active. More muscle means better blood sugar regulation, less fat storage, and more stable energy throughout the day.
Supports sleep and mood. Strength training increases serotonin and reduces cortisol over time. Women who lift consistently report better sleep quality and lower rates of anxiety and depression.
Why Most Women Don't Experience These Benefits
The problem isn't strength training itself — it's how it's programmed. Most gym programmes are designed for younger men, or for aesthetics, not hormonal health. They don't account for:
- Nervous system recovery capacity (which changes in menopause)
- Training periodisation around cycle phases (in perimenopause, cycles are irregular but still present)
- The importance of managing training load to avoid cortisol spikes
- The difference between fatigue and productive stress
This is why training smarter matters more than training harder.
What Hormone-Aware Training Looks Like
At Mettle Fitness, we structure every programme around three principles:
- Progressive overload — gradual, consistent increases in challenge to drive adaptation without overload
- Nervous system recovery — built-in recovery sessions and deload weeks to prevent burnout
- Phase awareness — understanding where you are in your hormonal cycle and adjusting intensity accordingly
The result? Women who consistently feel stronger, sleep better, and have more energy — not less.
