The Claim

Twelve weeks of progressive resistance training is associated with 25–43% increases in one-repetition maximum strength for major lower and upper body exercises in postmenopausal women, with similar improvements observed in both healthy individuals and breast cancer survivors.

Source: Skeletal muscle mass, strength, and physical performance gains are similar between healthy postmenopausal women and postmenopausal breast cancer survivors after 12 weeks of resistance exercise training

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.

In plain English

Doing strength training for 12 weeks can boost muscle strength by about a quarter to nearly half in women after menopause — whether they're healthy or have survived breast cancer.
