An exercise addiction may not be considered a bad thing to most people, but this addiction can have several harmful consequences. First exercising is maladaptive, it can cause a person to not have adequate rest, and also develop an eating disorder.Exercise is considered to be both physically and psychologically beneficial to health(Bouchard et al., 1994). However, a few people may exercise without limits and to damaging degrees, propelling researchers to agree that exercise could, in some cases,be harmful (Yates, 1991; Szabo, 1995, 1998, 2000) and become addictive (Griffiths,1997).
