Perimenopause is not the time to back away from the weights rack — it’s the time to lean in. As estrogen levels fluctuate, we naturally lose lean muscle mass and bone density. This loss starts in our 30s but accelerates during perimenopause, making strength training one of the most important investments you can make in your future health.
Why Strength Training Matters Now More Than Ever
Research from Dr. Stacy Sims and Dr. Marie-Claire Haver shows that as estrogen declines, our bodies become less efficient at building and maintaining muscle. Without intervention, women can lose up to 8% of muscle mass per decade, and bone density loss increases the risk of osteoporosis.
Strength training works like a protective shield:
Builds and maintains muscle mass to keep metabolism humming
Improves bone density to reduce fracture risk
Boosts insulin sensitivity and supports healthy blood sugar regulation
Enhances balance and coordination, reducing the chance of falls
Supports mental health, improving mood and reducing anxiety
It’s Not About Bulking Up
A common fear is that lifting weights will make you bulky. In reality, hormonal changes in perimenopause make it harder to build large muscles. Instead, lifting weights gives you a toned, strong, and functional body that can carry you through the decades ahead.
How to Start (and Stick With It)
You don’t need to spend hours in the gym. Two to three targeted sessions per week, using weights that feel challenging by the last few reps, are enough to see results.
Tips to start:
Focus on big movements: squats, deadlifts, push-ups, rows
Use resistance that challenges you while keeping form safe
Prioritise recovery — rest days and gentle movement matter
Pair strength with good nutrition (especially protein)
The Long Game
Think of strength training as your non-negotiable self-care tool. It’s not just about looking good — it’s about moving well, ageing strong, and feeling confident in your body.
