Why and How Should I Exercise? A Content Analysis of Popular Magazines.

In this study, we investigated how exercise is portrayed in popular, non-fitness focused magazines targeting various audiences. Ten popular magazines were selected based on target audience (Teens, Young Adults, Family, Middle-Aged Adults, Older Adults). Ten digital articles from each magazine's health/fitness section were coded for the primary reason to exercise, the frequency, intensity, time, and type of exercise recommended, and whether their recommendations were evidence-based. Frequencies were calculated by target audience. The primary reason for exercise differed by audience, with appearance and fitness empha- sized by magazines targeting younger audiences, and mental health/quality of life emphasized in magazines targeting older adults. Over half of the articles described exercises that should be completed 2x-3x/week for <10 minutes. Articles frequently recommended circuit workouts that could be completed at moderate or self-selected intensity. Only 10% of articles cited peer- reviewed evidence. Results showed popular magazines often represent exercise as something that can be completed in a short time frame with meaningful benefits. However, an overemphasis on appearance in young adults is apparent, which could undermine intrinsic mo- tivation and behavior. Improved communication between researchers and popular magazines is needed to promote sharing of credible, evidence-based exercise content with the public.
