Most community-based physical activity interventions for older adults prescribe class-based activities that may not appeal to everyone. This paper describes physical activity format preferences in a sample of 98 older adults (mean age = 76 ± 8 years) enrolled in an exercise promotion program encouraging participation in class-based activities offered by the community; the study explores how these preferences are related to activity adoption and maintenance. Thirty-four percent of respondents preferred to exercise individually. 28% preferred to exercise in a group, and 39% had no preference. Those who preferred exercising individually were less likely to adopt a new class than those who preferred to exercise in a group and those who had no preference (p < .01). Programs taking into account individual preferences may be more successful than those offering specific formats.
