Social network sites (SNSs) such as Facebook have the potential to persuade people to adopt a lifestyle based on exercise
and healthy nutrition. We report the findings of a qualitative study of an SNS for bodybuilders, looking at how bodybuilders
present themselves online and how they orchestrate the SNS with their offline activities. Discussing the persuasive element
of appreciation, we aim to extend previous work on persuasion in web 2.0 technologies.
