Strength at Every Stage of Life: The Complete Guide for Women
Why Strength Training is the Key to a Stronger, Healthier Life
"On average, every healthy Australian woman will lose 2.5kg of muscle every decade after 30"
Whether you're a teenager, in your 20s or 30s, pregnant, peri-menopausal, or postmenopausal the number 1 goal of every fitness program should be to build muscle or slow the rate of this muscle loss.
Yet many women avoid strength training, thinking it's unnecessary or fearing they'll get bulky. The truth is that strength training is the most powerful tool for maintaining muscle, boosting metabolism, and ageing confidently.

If you've ever felt:
- Confused about how to train at your current life stage
- Frustrated with weight gain, fatigue, or feeling weaker
- Unsure if lifting weights is "right" for women
- Worried about bone density, muscle loss, or metabolism slowing down
This guide will walk you through how to train at every stage of life, what to expect, and how to maximise results for strength and longevity.
What Happens If You Ignore Strength Training?
Women naturally lose muscle mass, strength, and bone density without strength training as they age.
This leads to:
- A slower metabolism → making weight management harder
- Increased risk of osteoporosis → leading to fractures and injuries
- Weaker joints and mobility issues → affecting independence later in life
- Higher body fat percentage → even if your diet hasn't changed
But here's the good news: Lifting weights can reverse these effects at ANY age.
