2022 May

The study looked at the same type of exercise program described in the claim and found that it really did increase muscle mass in middle-aged women, just like the claim says.

Similar Assertions

Doing full-body strength training three times a week for three months helps older adults, even those over 85, gain about 2% more muscle — and it works just as well for the very elderly as it does for the 'younger' elderly.

Older women who lift weights—even just one arm or leg at a time—gain muscle and fight off the natural muscle loss that comes with aging.

If healthy guys between 18 and 40 lift weights regularly for at least two weeks up to a year, they typically gain about 1.5 kilograms of muscle—no matter what kind of weight routine they follow.

When older women lift weights for 8 weeks, their muscles don’t get much bigger, but they do get stronger and walk faster—so it seems like something other than bigger muscles is helping them move better.

After doing strength training for 8 weeks, older women got stronger and their muscles worked better—but their muscles didn’t get bigger. This suggests their brains and bodies got better at using the muscles they already had, not at making new muscle.
