When older men and women over 60 do strength training, men tend to gain more total muscle mass than women, but when you account for their starting size, both sexes improve at about the same rate.

When older men and women over 60 do strength training, the men tend to get stronger in their arms and legs than the women do, even when they’re doing the same workouts.

When older men and women over 60 start lifting weights, women tend to get stronger faster relative to how strong they were at the start—especially in their arms and legs—compared to men doing the same workout.

When older adults (60+) do strength training, men and women gain muscle and get stronger in basically the same way—no big differences between the sexes.

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.

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.
