Simone Biles has arguably been the biggest focus of these Tokyo Olympics, and she's barely even competed---after having withdrawn shortly after the all-around gymnastics competition began last week.

Biles stayed away from several more gymnastics events in Tokyo, but she's coming back to the gym for one last shot at a medal:  she'll compete Tuesday on the beam.

Where the bright spotlights of Olympic pressure will be squarely on Biles.

Dominque Moceanu is a gold medal winning gymnast who was on the 1996 United States gymnastics team (known as the "Magnificent Seven"), she was the youngest member of that team; currently she's a gymnastics coach.
