Gymnast Simone Biles Becomes First Woman To Land Triple-Double

American gymnast Simone Biles made history as she landed a triple twisting double flip, commonly known as a triple-double at the U.S. Gymnastics Championship, in Kansas City of Missouri, US.
With this she has become the first woman to do so in women’s gymnastics competition.
Her winning performance included two skills: a triple-double (two flips with three twists) on floor exercise and a double-double dismount (two flips with two twists) on balance beam.
