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.

82%

If healthy adult men do resistance training for more than two weeks, they will reliably gain about 1.5 kilograms of muscle. This shows that lifting weights is a very effective way to build muscle overall, no matter how you measure it.

78%

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.

78%

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.

77%

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.
