n studying why people opt to exercise or not, scientists often and understandably focus on individual psychology and situations. But increasingly, exercise scientists are also looking into broader factors that can have a bearing, including our social relationships and whether being single, married, childless or employed is likely to affect exercise behavior.
The results of past studies on this subject have been alternately predictable and startling. Single men and women, for instance, generally exercise far more than do married people, although divorce can change that. Men typically exercise more after a marriage ends; women in that situation frequently exercise less. Meanwhile, employed men, even those with desk jobs, usually exercise more than men who are unemployed.
