Similar Assertions

Doing strength training three times a week for three months helps both healthy postmenopausal women and breast cancer survivors gain muscle and get stronger — and both groups benefit about the same.

Doing strength training for 12 weeks may help postmenopausal women — both healthy ones and breast cancer survivors — move better, walk farther, and get up and go faster.

88%

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.

For young women, doing resistance training with lighter weights for 10 weeks can build leg strength just as well as training with heavier weights, with strength gains around 10-16%.

Working out with weights can help older women build muscle and get stronger, no matter how exactly they do the workouts or which group they're in.
