This International Women's Day, we're celebrating strong women who broke barriers in the powerlifting, Olympic weightlifting, and bodybuilding worlds over the past few decades.

After checking out Muscle & Fitness'  Strongest Men to Ever Walk the Earth, we wanted to feature some of the strongest women in history. So we picked the brains of staffers at Men's Fitness, Muscle & Fitness, Muscle & Fitness Hers, and Flex to gather up their list of the strongest women who ever walked the earth. Read about these tough-as-nails women—listed in no particular order—who paved the way for the CrossFitting, bodybuilding, powerlifting women of today.
