The Claim
Resistance training with free weights performed twice weekly for 20 weeks significantly improves 1-repetition maximum strength in squat and bench press among middle-aged women aged 40–60, regardless of menopausal status, with effect sizes ranging from moderate to strong (d = 0.66–1.64), and these strength gains are primarily driven by neuromuscular adaptation rather than hormonal status.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Middle-aged women aged 40–60 who perform free weight resistance training twice a week for 20 weeks experience measurable increases in their maximum strength for squat and bench press, and these gains occur regardless of menopausal status due to improvements in nerve-muscle coordination, not hormone levels.

When middle-aged women lift heavy weights, their brain sends stronger and more coordinated signals to their muscles, allowing more muscle fibers to contract at once. This happens even if their muscles don't get bigger, and it doesn't matter if they've gone through menopause or not. The muscles become better at responding to the brain's commands, which makes them stronger.
What the research says
1 studyMiddle-aged women, whether or not they’ve gone through menopause, got significantly stronger in squats and bench presses after doing free weight workouts twice a week for 20 weeks. Their muscles got better at listening to their brain, not because of hormones.
