17. Oksana Chusovitina
This Ukrainian gymnast’s career just doesn’t make sense. Firstly, gymnasts usually peak in their late teens. By the time they enter their 20s, they’re usually entering the twilight of their careers. Look at Simone Biles’s career. Chusovitina is 44 and is hoping to make it to her eighth Olympic Games.

Very few elite gymnasts are able to return to the sport after giving birth. However, Chusovitina did this as well, redefining what it means to be a gymnast in the process. The three-time World Champion is an Olympic Silver medalist. If she makes it to Tokyo it will be an incredible story.
