Similar Assertions

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.

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.

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%.

Doing full-body strength training three times a week for three months can boost thigh muscle size by about 10–11% in older adults, even for those over 85 — showing that very old age doesn’t stop muscles from growing with exercise.
