Operational criteria for primary exercise dependence6

1. Preoccupation with exercise becomes stereotyped and routine
2. Significant withdrawal symptoms in the absence of exercise (e.g. mood swings, irritability, insomnia)
3. The preoccupation causes clinically significant distress or impairment in their physical, social, occupational, or other important areas of functioning.
4. The preoccupation with exercise is not better accounted for by another mental disorder (e.g. as a means of losing weight or controlling calorie intake as in an eating disorder).
