The scientists also created a separate questionnaire with detailed queries about exercise habits, including how often and intensely the men worked out each week. The scientists used their responses to stratify the men based on both the extent and intensity of their workouts. They wound up with groups whose weekly exercise was short, moderately lengthy or quite prolonged, and separately whose weekly exercise was light, moderate or extremely intense. They also categorized the men according to their answers about their sex lives, creating groups with relatively high, moderate or low libidos. Finally, they compared the men’s exercise habits to their reported interest and engagement in sex.
