The one type of exercise a trainer wants every woman over 40 to try—and you can start sitting down

A woman performs jumps in an apartment over an exercise mat.

“The first thing that goes as we age is actually power, not strength. You lose that ability to jump,” says personal trainer Angie Wilkinson, aka the Strength Queen.
