What the Largest-Ever Resistance Training Review Revealed About Midlife Women’s Health
Why Strength Training Matters More Than Ever in Midlife
A major 2026 review from the American College of Sports Medicine analysed 137 systematic reviews involving more than 30,000 participants, making it the most comprehensive review of resistance training ever conducted. The findings were clear: strength training improves muscle strength, physical function, balance, power and overall health across adulthood.¹
For women in midlife, these benefits become particularly important.
The hormonal changes that occur during perimenopause and menopause can accelerate the loss of muscle mass and bone density. This can affect strength, mobility, metabolic health and long-term independence. Strength training provides a powerful way to counter many of these changes.
Research shows that regular resistance training can:
Help maintain and build muscle mass
Support bone health and bone density
Improve balance and physical function
Enhance insulin sensitivity and metabolic health
Support healthy ageing and independence
Improve confidence, energy and overall quality of life
Perhaps the most encouraging finding from the ACSM review is that consistency matters more than perfection. You do not need hours in the gym or a complicated programme. Training all major muscle groups at least twice per week can produce meaningful improvements in strength, function and health.
In midlife, strength training is not simply about building muscle. It is an investment in your future health, resilience and independence.
