All-around: What to watch
Simone Biles has won three consecutive world titles and is the favorite for the Olympic all-around gold.
VAULT
The Amanar, in which Biles does 2½ twists and makes a blind landing, is a vault tried by few gymnasts.
FLOOR
She will do “the Biles,” a pass with a double layout with a halftwist and a blind landing.
UNEVEN BARS
The one event in which Biles didn’t advance to the individual finals. Don’t struggle on lower bar or opening handstand.
BALANCE BEAM
Biles’ opening (a 2½-revolution turn) and dismount (a full-twisting double tuck) are two of the most difficult in the world.
