Tatum was athletic while growing up, playing football, soccer, track, baseball, and performing martial arts; he has said that "girls were always [his] biggest distraction in school." As a child, he practiced wuzuquan kung fu under the lineage of 10th dan Grandmaster Chee Kim Thong. Tatum spent most of his teenage years in the Tampa, Florida area and initially attended Gaither High School before going to Tampa Catholic High School. He graduated in 1998 and was voted most athletic. Afterward, Tatum attended Glenville State College in Glenville, West Virginia on a football scholarship, but dropped out. He returned home and started working odd jobs. US Weekly reported that around this time Tatum began working as a stripper at a local nightclub, under the name "Chan Crawford." In 2010, he told an Australian newspaper that he would like to make a movie about his experiences as a stripper. He later moved to Miami, where he was discovered on the street by a model talent scout.
