Using data from a supplement to the 1995 National Health Interview Survey, this article examines the relationship among three major work and family roles—marriage, parenthood, and employment—and time spent on exercise among American men and women ages 18 to 64 (N = 13,496). As the time availability perspective suggests, work and family roles curtail time for exercise. Married adults spend less time on exercising than unmarried adults. Although the number of children is not related to time spent on exercising, having children under age 5 is negatively associated with exercising. Long hours of employment are also related to less time spent on exercising, although the effect is small. Across the board, women spend less time on exercising than men, but the negative association of work and family roles, especially the role of spouse, with time for exercise is greater for men than for women.
