Career highlight

Last year was Wieber's first at senior level - but what an impact she made. She signalled her arrival by beating then-world champion Aliya Mustafina at the American Cup on her international debut.

Wieber then took the individual all-around title at the World Championships and helped the USA to team gold.

Career background

Wieber got her first taste of gymnastics as a four-year-old after her parents put her in a recreational class because they noticed she had unusually large muscles for a young child.
