Rheingans was an NCAA champion in 1975 for North Dakota State University and wrestled in the 1976 Olympics, placing fourth. He qualified for the Olympic team in 1980, but did not compete due to the United States boycott against the Soviet Union.
Rheingans entered professional wrestling with Verne Gagne's American Wrestling Association in 1983, where he appeared until the organization folded in 1991. He also wrestled briefly for the WWF as an enhancement talent in 1986, occasionally for New Japan Pro Wrestling from 1989–1991, and for various independent promotions in the Minnesota area during the early half of the 1990s.
In addition to coaching amateur wrestlers throughout his career, Rheingans also trained numerous professional wrestlers. Some of his well-known students include Vader, John "Bradshaw" Layfield, The Nasty Boys, Jerry Lynn, Tom Zenk, Joe Hennig and Tori. Rheingans also served as the head trainer for the short-lived Ladies Professional Wrestling Association.
Rheingans was inducted into the George Tragos/Lou Thesz Professional Wrestling Hall of Fame in 2004.
