The Claim
In postmenopausal women, regardless of breast cancer history, engaging in progressive resistance exercise training three times per week for 12 weeks is associated with an approximate 5–8% increase in quadriceps muscle thickness as measured by ultrasound imaging.
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.
If postmenopausal women do strength training three times a week for three months, their thigh muscles get about 5 to 8% thicker — whether or not they’ve had breast cancer.

What the research says
1 studyThe study looked at the same type of strength training described in the claim and found it helped increase thigh muscle size in postmenopausal women, whether or not they had breast cancer.
