Chellsie Marie Memmel (born June 23, 1988 in
Milwaukee, Wisconsin) is a U.S. gymnast. She started
gymnastics as a young child because her parents were
both gymnastics coaches and she grew up playing in
the gym. She began competing as an elite in 2000.
Chellsie has two skills named after her: a double
turn with leg fully extended in a "Y" on floor and a
piked barani on beam. Chellsie is also the third
woman in the world to complete a Dos Santos, an
Arabian double front in the piked position. Chellsie
became the third American woman in gymnastics (after
Kim Zmeskal and Shannon Miller) to become the World
Champion in the All-Around competition. Shawn
Johnson has since repeated this in 2007.
