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.
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.
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.
