This is Dana Volmer, one of the best butterfliers in history with a career starting on the international level at age 13, and later becoming the first woman to break :56 in the long course 100 meter fly. She showed phenomenal grit in making the 2004 Olympic team and then NOT making the 2008 team, then coming back to win the 2012 Olympic event and break the world record in London. This position is called the "YPress."
