What Women Over 40 Should Know About Strength Training
Never focused on strength training before and don't know where to start? You're not alone if you're asking "Why should I begin lifting weights and what's the safest way to start?"
Key Takeaways
Strength training becomes even more crucial after 40, helping combat age-related muscle loss, bone density decline, and hormonal changes.
Women lose 3-8% of muscle mass per decade after age 30
Resistance training can reverse bone density loss and reduce fracture risk by 40%
Strength training helps manage menopause symptoms and boosts metabolism
Why Your Body Needs Strength Training After 40
Declining estrogen during perimenopause and menopause doesn't just cause hot flashes—it directly impacts your bones, muscles, and metabolism. Without intervention, women can lose up to 20% of bone density in the 5-7 years following menopause.
Strength training acts as a powerful countermeasure. When you lift weights, you're not just building muscle—you're sending signals to your bones to stay strong and dense. During perimenopause, estrogen levels first become erratic and begin to decline. By menopause, women experience an 80–90% reduction in estrogen compared to premenopausal levels, removing a key protector of bone health.
What Are the Biggest Benefits for Women Over 40?
Beyond the obvious strength gains, resistance training offers unique advantages for women in their 40s and beyond:
Metabolism boost: Pound for pound, muscle burns more calories at rest than fat tissue. Muscle burns between 6 - 10 calories per pound per day whereas fat burns 2–3 calories per pound per day at rest. Building muscle helps combat the age-related metabolic slowdown that occurs as we lose muscle mass over time.
Mood improvement: Strength training can reduce anxiety and depression—common during the perimenopause transition when fluctuating estrogen and declining progesterone disrupt natural mood-regulating mechanisms.”
Better sleep: Regular resistance exercise helps regulate hormones and can improve sleep quality, which affects up to 60% of perimenopausal women.
How Should You Start Strength Training After 40?
Focus on compound movements that work multiple muscle groups: squats, deadlifts, rows, and presses. Start with bodyweight or light weights 2-3 times per week for about 20-40 minutes, allowing at least one rest day between sessions.
Progressive overload is key—gradually increase weight, reps, or sets every 2-3 weeks. Your muscles adapt quickly, so consistency trumps intensity when starting out.

Q: Can I start strength training during menopause? A: Absolutely. Strength training is one of the most effective ways to manage menopause symptoms and protect long-term health.
Q: How long before I see results? A: Most women notice increased energy within 2-3 weeks, with visible strength improvements in 6-8 weeks.
