[1][2] Hong lived in Blue Springs, Missouri, and trained at Great American Gymnastics Express (GAGE) for four years.

Hong's skill as an all-around athlete without a weak event enabled her to be named, along with Jana Bieger and Corrie Lothrop, as one of three alternates for the U.S. Olympic team.

This made medalists of all four American gymnasts (Bridget Sloan, Kayla Williams and Rebecca Bross in addition to Hong) in the women's competition.

In early March 2010, Hong tore the anterior cruciate ligament in her right knee at the National Team training camp as she landed a vault.
