The Claim

Resistance training with free weights at 6–8 sets per muscle group per week does not reduce fat mass in post-menopausal middle-aged women, while pre-menopausal women experience a moderate reduction in fat mass (d = 0.57), indicating that fat loss in response to this training volume is dependent on menopausal status.

Cause and effect
1 study reviewed
In plain English

In middle-aged women, resistance training with free weights at 6–8 sets per muscle group per week does not reduce fat mass after menopause, but it does reduce fat mass moderately before menopause.

See the scientific wording

Resistance training with free weights at 6–8 sets per muscle group per week does not reduce fat mass in post-menopausal middle-aged women, while pre-menopausal women experience a moderate reduction (d = 0.57), suggesting fat loss requires higher training volume or hormonal sensitivity.

Why this might work

In women with normal estrogen levels, resistance training triggers muscle growth, which increases energy use and reduces fat stores. In women with low estrogen, the same training does not trigger enough muscle growth, so fat stores do not decrease.

    Women who haven’t gone through menopause lost body fat and gained muscle from the same workout that didn’t change body fat in women who had gone through menopause — suggesting hormones matter for fat loss.
