In 1996 and 1997, Hingst won the league with Zehlendorf, but they failed to win their promotion play-offs both years.

In 2007, Hingst moved to the Swedish first division side Djurgårdens IF Dam, where she played for two years, finishing runner-up in the league both seasons. She returned to Germany in 2009, joining 1. FFC Frankfurt. In her third season at the club, she won the 2011 German Cup.
